Corrections and Retractions

Retraction and Correction Policy

Jurnal Statistika dan Aplikasinya (JSA) is committed to keeping the published record accurate and complete. When errors or ethical problems are found in a published article, the journal will publish a correction, an expression of concern, or a retraction. This policy follows the COPE Retraction Guidelines.

Published articles are not changed or deleted without a public notice. Every notice is linked to the original article, has its own DOI where possible, and is listed in the table of contents of the current issue.

1. Withdrawal of a Manuscript Before Publication

Authors may withdraw a manuscript before peer review starts by sending a request to the editor.
After peer review has started, authors may withdraw only for a serious reason, such as a major error in the data. The request must be signed by all authors and sent by the corresponding author, using the email address registered in the submission system, to jsa@unj.ac.id.
Authors must not submit the manuscript to another journal until the withdrawal is confirmed by the editor.
Information about any withdrawal fee is available on the Author Fee page.

2. Correction

A correction is published when a small part of an article is wrong, but the main findings and conclusions are still reliable. Examples include errors in an author name or affiliation, a table, a figure, or a reference.

Erratum: corrects an error made by the journal during production.
Corrigendum: corrects an error made by the authors.

The correction notice explains what was changed. The corrected article is published with a note that links to the correction notice.

3. Expression of Concern

The editor may publish an expression of concern when there are serious doubts about an article, but the evidence is not yet clear. For example:

an investigation by the authors' institution is still in progress;
there is evidence of possible misconduct, but it is not conclusive;
the authors' institution does not respond to the journal's request for an investigation.

After the case is resolved, the expression of concern is followed by a correction, a retraction, or a notice that the concern has been removed.

4. Retraction

The editor will retract an article if:

there is clear evidence that the findings are not reliable, because of misconduct (such as making up or changing data) or honest error (such as a serious calculation error);
the findings were published before in another journal without proper citation, permission, or reason (duplicate publication);
the article contains plagiarism;
the community engagement program or research was unethical, for example without the consent of the community partner or participants;
the article contains a serious undisclosed conflict of interest that affects the reliability of the work;
the authorship or peer review process was manipulated.

How a retraction is done:

The editor investigates the case following the COPE flowcharts and gives the authors a chance to respond. See our Allegation of Research Misconduct policy.
A retraction notice titled "Retraction: [article title]" is published. It states who asked for the retraction (the authors, the editor, or both) and the reason.
The original article stays online so the record is complete, but it is clearly marked "RETRACTED" on the article page and on every page of the PDF.
The article metadata, including the DOI record at Crossref, is updated to show the retraction.

5. Removal

In rare cases, an article may need to be removed from the website. This happens only for legal reasons (such as defamation or copyright infringement) or when the content may cause serious harm, such as exposing the personal data of participants. The title and authors stay online with a notice explaining why the article was removed.

6. Requesting a Correction or Retraction

Authors, readers, or institutions can request a correction or retraction by contacting the Chief Editor at jsa@unj.ac.id. Please include the article title, the DOI, and a clear explanation of the problem.
