Q: Who is an expert when it comes to statistical analysis?
When submitting a manuscript, I found a question that asks if the statistical analysis was done by experts. Actually who is the “expert”?
Many journals want statistical analysis in their papers to be done by statistical experts. A statistical expert is a statistician, that is, anyone with a degree in statistics, who can verify that the analysis done in the manuscript is correct. Some journals may even want authors to upload certificates from statistical experts if their manuscript contains statistics. There are some professional statisticians who offer statistical analysis as a service. However, it should also be fine if you can get someone from your university's statistics department to do it for you. You can also ask your professors or senior colleagues if they know of some reliable statistical experts who offer this service.
However, before you do that, please go through the author guidelines of your journal carefully to see if they have any other specifications about statistical analysis.
