What should I do if the sci paper requires a statistical certificate?

First of all, we should find professional statisticians, preferably teachers in the statistics department or teachers who have published at least many biostatistics articles or scientific research service companies. Generally, there are abundant editors in various disciplines. Secondly, send the article to them, and they will review all the methods and conclusions related to biometrics involved in the article. Finally, the auditor will issue a certificate, and the author can prepare it in advance for the auditor to modify the signature.
