WebMay 1, 2024 · Hi, I was using HypothesisTests.jl and noticed minor, but possibly important differences in the p-value estimate between julia and two other packages when using Fisher’s exact test. In this example, matlab and R users might claim a significant result, whereas the julia user might not. This is a fairly common test, and it would be great if … WebThis is also known as the chi-square test of independence. Fisher's exact test is used to calculate P values for small sample sizes. It was created for a specific (and rare) …
WebFisher's exact test, as its name implies, always gives an exact P value and works fine with small sample sizes. Fisher's test (unlike chi-square) is very hard to calculate by hand, but is easy to compute with a computer. Most statistical books advise using it instead of chi-square test. If you choose Fisher's test, but your values are huge ... WebThis is a Fisher exact test calculator for a 2 x 2 contingency table.
