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.

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.
