Error when I try to use Fisher's exact test

ProbitCamel1077 — Mon, 28 Apr 2025 03:24:43 GMT

I want to ask the comments when I try to use Fisher's exact test.

I am using IMP Student Edition 18.

When I push the tab of Fisher's exact test in the analysis of bivariate relationships,

the comment " it might take a long time", and I cannot get the resullt of the test.

How can I do Fisher's exact test?

Hi @ProbitCamel1077. Fisher's exact test is computationally intensive and can take a while to compute if your sample size is large. For reference, running a 3x4 Fishers exact test on the attached data table of 2,001 rows takes 3.5 minutes on my Macbook Pro with M1 Pro processor. Larger data sets can take substantially longer.

How long have you let the test run before cancelling it?

Thank you for your reply.

I had let the test for 1hour.

It might be the problem of my PC.

I'll try the test with more powerful PC.
