No, keywords cannot be changed after a paper's submission, because they are the crucial element in deciding who the editor in charge will be, and therefore how the peer review process is determined. Apart from selecting the keywords, at submission time authors can also assign a value to each of them (25, 50, 75 or 100) to establish their relevance to the subject matter covered in the preprint.

No.Once submitted the article should not be replaced, if the new version differs substantially the article can be withdrawn and resubmitted.

The person making the submission, who is notified of decisions and requested to take action in the various steps of the editorial process. If the paper is accepted for publication the corresponding author will be asked to accept a copyright formonline on behalf of themselves and their coauthors. By accepting the copyright form, it is assumed that all authors have received the final version of the contribution, have agreed to it being submitted to the journal and agree to the terms of the copyright form. Please note: on the publisher's page the corresponding author will be the first name listed in the .pdf of the article.

Yes. The corresponding author of articles submitted to JSTAT is responsible for the accuracy of information in regards to coauthors. If coauthors are added/removed after submission they and the editorial office should be informed accordingly.

The Editorial Board is composed of distinguished and active scientists in the field. Editors in JHEP are selected automatically through an algorithm based on the keywords selected by the authors at submission time. After the paper is assigned to an editor, the editor usually seeks the advice of an expert reviewer, but may equally well decide to review the paper autonomously. Editors and referees generally operate anonymously in order to guarantee an unbiased handling of articles, but are free to reveal their identity to the authors if they so wish.

Yes, upon submission you can use the 'write to editor' button to suggest suitable referees for your article, however the editor in charge of the article is under no obligation to select them.

The editor in charge and the editorial Office are carefully following the processing of your paper and will do their best in order to avoid any undue delay, while favoring quality over speed. It can be a challenge to ensure timely responses, and it can happen that the process takes longer than planned. You can at any time get in touch with the editor in charge to inquire about the status ('write to editor' button on the preprint status page).

No, changes of authorship or in the order of authors listed will not be accepted by the publisher. The only way to modify the author list of a published article is by means of an erratum.

The only way to modify a published paper is by means of an erratum\addendum. https://jstat.sissa.it/jstat/help/helpLoader.jsp?pgType=author#erratum

Yes. JSTAT encourages authors to submit to arXiv their article accepted for publication including all changes made as a result of the peer review process, but excluding any other editing, typesetting or other changes made by IOP Publishing and/or its licensors. Please select the 'non-exclusive licence to distribute' offered by arXiv when uploading the article. We recommend the inclusion of the DOI when citing the published manuscript.

Authors can request a reconsideration after a rejection decision. Upon another rejection, authors can request an appeal. Appeals must be scientifically justified and not polemic. Appeals can be assigned to the same editor or a new one on a case by case basis. Second appeals will not be considered unless there is a clear history of unfair treatment of the manuscript. Appeals should be requested within a year's time, after which articles will be considered as new submissions. To guarantee the fair treatment of papers, the processing of appeals is supervised by the scientific directors.

Not suitable decisions cannot be appealed. This kind of decision in fact indicates that the paper does not fall within the scope of the Journal and cannot be considered for publication, either because the subject matter is not relevant for it, or because it does not meet its standards.

JSTAT strongly encourages posting data files and similar supplementary material to publicly-accessible, discipline-specific, community-recognised repositories that comply with the FAIR principles as much as possible.
In cases where a suitable discipline-specific resource does not exist, such files may be submitted to a generalist repository (for example, Zenodo), including any such repositories provided by universities, funders or institutions for their affiliated researchers.
Authors may also wish to explore repository registries such as FAIRsharing.org and re3data.org

Supplementary material should should conform to the FAIR principles as much as possible.

Use graphicx: include the graphicx package (\usepackage{graphicx}) at the start of the latex file, immediately after the documentclass statement, then, include the figure in the body of your article with the \includegraphics command. Width, height and other options (scale, angle, ... ) can be also be specified.

\includegraphics[width=60mm,height=70mm]{myfig.eps}

NB: File names are case sensitive and must not contain spaces

You can use the lineno package which provides line-numbering and various options for customization as shown in the following example.

\usepackage{lineno}
\begin{document}
\setpagewiselinenumbers
\linenumbers
...

You can use graphicx (include the graphicx package at the start of the latex file) but you must also add \pdfoutput=1 immediately after the \documentclass command as shown in the following example:

\documentclass[11pt,a4paper]{article}
\pdfoutput=1
\usepackage{graphicx}
...

If the figure file size is very large, the generation of the pdf will take longer than normal which may result in a system timeout and generate an empty .pdf file (see "A blank pdf file has been generated").

The use of very high resolution figures may affect the size of the final .pdf file, increase the download time of your article and increase the time needed to visualize the page containing a very high resolution figure.

Figures can be used to improve your article, and their readability is very important. Readability does not imply high resolution, so a tradeoff should be made in order not to create an unnecessarily large .pdf file.

Yes

1. The \documentclass command and all its options must be typed on a single line.

2. If you use pdfex you must add \pdfoutput=1 immediately after the \documentclass command.

3. File names must not contain spaces and are case sensitive

4. If you use Bibtex the bib file must be included in the submitted archive

To include figures in your Word document, choose the "From file..." option, from the "Insert, Picture" menu:

Figures should be referenced in the text and always need a caption describing their contents.

All the figures must also be included as separate files (.png, .jpeg, .pdf) in the compressed archive.

If the figure file size is very large, the generation of the pdf will take longer than normal which may result in a system timeout and generate an empty .pdf file (see "A blank pdf file has been generated").

The use of very high resolution figures may affect the size of the final .pdf file, increase the download time of your article and increase the time needed to visualize the page containing a very high resolution figure.

Figures can be used to improve your article, and their readability is very important. Readability does not imply high resolution, so a tradeoff should be made in order not to create an unnecessarily large .pdf file.

If your submission contains more than 1 file, you need to submit a tar.gz or zip archive containing all the necessary files for a successful compilation (see "What files do I need in my archive")

First locate the folder ('mypaper' in our example) that contains all the files that need to be compressed.

Linux/MAC tar.gz:
- open a terminal window, and navigate to the 'mypaper' directory (es. $ cd mypaper/)
- the main tex (or .docx) file must be in the 'mypaper' directory (and not in a subdirectory of it)
- type $ tar -cvzf article.tar.gz *
- this creates an archive called "article.tar.gz" containing all files and folders in the 'mypaper' directory

Linux/MAC zip:
- open a terminal window, and navigate to the 'mypaper' directory (es. $ cd mypaper/)
- the main tex (or .docx) file must be in the 'mypaper' directory (and not in a subdirectory of it)
- type $ zip article.zip *
- this creates an archive called "article.zip" containing all files and folders in the 'mypaper' directory

Windows/MAC zip:
- there are various programs (winzip, stuffit) that produce zip files on windows/Mac. The important point to remember is that the main tex file must be in the 'mypaper' directory (and not in a subdirectory of it).

Master file:
TeX/Latex submission - it is the .tex file to compile.
Word submission - it is the .docx file of the article.
note: the master file must be placed in the root directory of the archive.

If two or more source files have the same extension (i.e. "main.tex" and "definition.tex", or "File1.docx" and "File2.docx"), when submitting your article you must specify the master file name in the appropriate field (Master file name:), otherwise the submission will fail.

All figure files:
The files of all the figures used in your article must be included.
Note for a Word submission, even if the figures are included in the .docx file, the figure source files must be included separately in the archive.

Other files:
- Bibliography files (e.g. .bbl, .bst, .bib. See "How do I include the bibliography in my document")
- any non-standard or customized packages used.
- some files related to the used packages (e.g. always include the .pk, .tfm and .t1, .t2, ..., files if you are using the feynmf package)
- the definition file(s) and many other.

Do not include: the pdf of your article, unused figures or any other unnecessary files (such as referee report ecc). Supplementary material can be uploaded separately after the archive upload (see "Supplementary material attached" in the JSTAT author pages),

Important notes on file names:
File names are case sensitive and must not contain spaces.

Yes. The maximum archive file size that is accepted for upload is 10MB

Please note that large tables, additional figures, computer programs, output files or video clips can be submitted as additional material, by clicking on the button "upload file" after the successful submission of the article (see "Supplementary material attached" in the JSTAT author pages).

See also the section "What files do I need in my archive" and "How do I create an archive file".

No. Please enusure that all file names do not contain spaces

Remember that if you change the name of the files included/referred in your Latex article (figures' name, bibliography file,...), then the main .tex file has to be updated accordingly.

Yes. If File1.eps is refered to in the Latex article, the system expects to find File1.eps and not file1.eps

Remember that if you change the name of the files included/referred in your Latex article (figures' name, bibliography file,...), then the main .tex file has to be updated accordingly.

.tex
.docx
.tar.gz
.zip

Other file types are not accepted.

Please note that only invited reviews can be submitted to JSTAT. Click "Submit a review" from the JSTAT home page, choose the review, and then follow the "Submission" instructions

Click "Submit a special issue" from the JSTAT home page, choose the special issue, and then follow the "Submission" instructions

Please refer to "File and archive preparation" and then follow the "Submission" instructions.

The figure below provides an example of a correctly compiled submission form.

The field "arXiv number" is not mandatory and your submission will not fail if you do not fill it.

The master file name must be provided when more than one .tex or .docx file is present in the submitted archive.

If it is not provided you will recieve the following error:
"The system is unable to find the master file"
and you should repeat the submission process specifying the master file name.

The figure below provides an example of a correctly compiled form.

• If you are submitting a preprint using the old arXiv number format you must choose a specific archive from the "xxx archive" pull-down menu.
• If you are submitting a preprint using the new arXiv number format, leave the "xxx archive" pull-down menu at the default setting "archive name".

The master file name must be provided when more than one .tex or .docx file is present in the submitted archive.

If it is not provided you will recieve the following error:
"The system is unable to find the master file"
and you should repeat the submission process specifying the master file name.

For questions about license and copyright please write to: permissions@iop.org

There are 6 checks for a successful submission:

Step 0.

The extension of the uploaded file is checked. The only extensions accepted are: .tex, .docx, .zip and .tar.gz.

Steps 1 and 2.

When a compressed archive file is submitted, the system checks that it is not corrupted and can be correctly uncompressed.

If the system can not uncompress and extract the files from your archive, it will trigger a submission error.

You can follow the instruction on "How do I create an archive file" to avoid submission problems.

Step 3.

File format checked. The uploaded file format is checked to see that it corresponds to the format selected by you

Steps 4 and 5.

The system searches for the master file and returns and error if it can not find it.

You can follow the instruction on "How do I create an archive file" to avoid submission problems.

Step 5.

The system compiles the Latex file (compilation errors may occur) or processes the Word document to create the pdf of the article. If the generation of the pdf takes too long (for example because of large figures included), a timeout may occur.

If you have a submission error in one of these steps, consult the section "The submission cannot be accepted by the system".

Remember that the submission can be completed only if your file compiles successfully on the JSTAT server. Therefore, please check the pdf generated by the system.

It means that the system can not locate the master file inside the submission archive, and it is probably placed inside a sub-directory of the archive.

The master file (.tex or .docx) must be placed in the root directory of the archive.

See "How do I create an archive file" for more information.

An error has occurred in one of the 6 steps of the upload process :

	0	The file you have uploaded is not supported by our system.
The uploaded file is not one of the accepted formats: TeX, LaTeX, .docx, .zip and .tar.gz.
	1/2	File compression: failed. You have submitted an incorrectly compressed file.
The submitted file/archive is badly compressed and the system is unable to extract the data. The file(s) should be recompressed and tested (by extracting the compressed files), before trying the submission again. See also "How do I create an archive file".
	1/2	Archive checked: failed. You have submitted an incorrectly archived file.
The submitted file/archive is badly compressed and the system is unable to extract the data. The file(s) should be recompressed and tested (by extracting the compressed files), before trying the submission again. See also "How do I create an archive file".
	3	File format checked: failed. The uploaded file format does not correspond to the format selected by you
The "source contribution format" selected (tex/doc/docx) does not match the actual format of the contribution being uploaded.
	3/4	File format checked: FAILED. The specified master file is missing from the submitted contribution
The master file name was not found in the submitted archive file. The master file MUST be in the root directory of the submission archive. Repeat the submission after checking that the master file is actually present in the root directory of the archive to be submitted.
		File format checked: FAILED. More than one doc contribution. Please specify master file name in submission form
The submitted archive comprises more than one .docx files. Repeat the submission procedure and specify in the field "master file" the name of the file for the preprint.
	3/4	File format: failed. Master file does not correspond to the format selected by you. Please ensure that the correct file extension (.docx) is included in the Master file name.
The master file name is not present in the submitted contribution or has a different extension than the one specified ("source contribution format"). Repeat the submission after checking that the correct master file is actually presenpresent in the root directory of the archive to be submitted.
	3/4	File preparation: FAILED. The system is unable to find the master file name so you MUST specify it in the submission form
The system is unable to identify the master file. Check that the master file is present in the root directory of the submitted archive. Repeat the submission and fill in the "master file name" field.
	4	File preparation: FAILED. Master file does NOT correspond to the format selected by you (.tex)
The format selected in the checkbox "source contribution format" does not match the format of the contribution that was actually submitted. Repeat the submission and select the correct format of your submission.
	4/5	Latex compilation timeout: the compilation has taken too long
The contribution can not be successfully compiled within a reasonable period of time. Try submitting again. If the document you want to submit compiles on your computer and you get this error also in your second attempt, then contact our editorial office with attached the document/archive you want to submit.
	5	File compilation checked: FAILED. There are some LATEX compilation ERRORS. Please check the log file
The Latex contribution can not be successfully completed becase of some Latex compilation errors. In the link "log file" you have access to the tex compilation log. Once the error is fixed, create a new archive file and repeat the submission.

The size of the submitted file exceeds the system limit of 10 MB.

Try to reduce the size of the archive file you are submitting see "What files do I need in my archive?" and repeat the submission including only the files that are strictly necessary your archive.

If the submitted archive or file includes a video or other files that can be viewed separately from the contribution, these can be submitted as separate attachments after contribution has been uploaded successfully.

The submitted file is empty. Please check the submitted archive file or try to recreate the archive file
(see "How do I create an archive file").

The main cause of this type of error is that the bibliography is not included correctly in your Latex article.

See the section "How to include the bibliography" for more information.

An error occurred whilst generating pdf file. Our technical staff have been informed automatically of the problem and it will be resolved as soon as possible. The author and the editor will be informed by the Editorial Office as soon as the files are available.

An error occured during the pdf generation.

Please inform the Editorial Office of the problem.

This problem is mainly caused by a timeout due to large images in the article. If this is the case, please use smaller sized images in future submissions.

This is usually due to a problem with a figure file (e.g. the figure is corrupted or has a technical problem).

Please inform the Editorial Office of the problem.

If this is the case, in future submissions, please check integrity of your figures before submission.

Please inform the Editorial Office of the problem.

• Latex submission: the figures are corrupted or need additional files/package not present in the archive.
  (see "What files do I need in my archive")
  
  
• MS-Word submission: there was a problem generating the pdf from Word. Please include all the figure source files in the archive and we will try to resolve the problem.

All figures should be cited in the text, therefore the misplacement should not affect the content of the article.

Please inform the Editorial Office if the problem affects the readability of your article.

Please inform the Editorial Office

For future submission please check that:

• the bibliography files are properly included
  (see "How to include the bibliography in your document")


• the bibliography style file (.bst) used to generate the bibliography is also included.

The master file (.tex or .docx) must be placed in the root directory of the archive.

See "The system is unable to find the master file".

If your Latex article uses .png, .jpg or .pdf figures, then a Pdflatex compilation is required.

You must add \pdfoutput=1 on a separate line immediately after the \documentclass command as shown in the following example:

\documentclass[11pt,a4paper]{article}
\pdfoutput=1
\usepackage{graphicx}
...

Remember that ps and eps images are not allowed in pdflatex.
(see also "Pdflatex")

See the section "What files do I need in my archive".

Latex compilation errors regarding figures are very frequent. The most common reasons are:

• The figures included in your article have extension .png .jpg or .pdf and \pdfoutput=1 is missing (see "Pdflatex")
  
  
• The file names contain spaces.
  (see "Can a file name contain spaces?")
  
  
• A figure is missing in the submitted archive.
  (see "How do I create an archive file")
  
  
• The figure file name does not match the one in the latex file.
  (Remember filenames are case sensitive and no spaces are allowed).

If the system can not locate the bibliography file, it will generate an error. The most common reasons are:

• the bibliography is included using the \include command.
  Please see "How do I include the bibliography in my document?"
  
  
• the bbl file is missing. In this case please include the bbl file in the archive for the submission.

The most common errors are:

• there are spaces in the filenames.
  Please see "Can a file name contain spaces?"
  
  
• the actual file name does not correspond to the one specified in the latex document.
  (Remember filenames are case sensitive and no spaces are allowed).

The \documentclass command and all its options must be typed on one line.

The following will produce an error:

\documentclass[a4paper,
11pt,
twocolumn]
{article}

The following is correct:

\documentclass[a4paper, 11pt, twocolumn] {article}
