WebThe basic idea behind exact tests is that they enumerate all possible tables that have the same margins, e.g., row sums and column sums. Then to compute the relevant statistics, e.g., X 2, G 2, odds-ratios, we look for all tables where the values are more extreme than the one we have observed.
WebBut, there is no equivalent post hoc test for Fisher's test. The only "post hoc" thing that comes to mind is to run all pairwise comparisons for the table, and correct the p-values accordingly with, e.g., the Bonferroni method. For a Chi square test, you could check the residuals or simply the expected-observed counts. WebSep 20, 2011 · Fisher's exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables [1]. The job of Fisher's exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn't found , or with bad computation.
WebApr 23, 2024 · The most common use of Fisher's exact test is for 2 × 2 tables, so that's mostly what I'll describe here.
