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. WebFishers’s LSD method is an alternative to other pairwise comparison methods (for post ANOVA analysis). This method controls the α -level error rate for each pairwise comparison so it does not control the family error rate. This procedure uses the t statistic for testing H 0: μ i = μ j for all i and j pairs. t = y ¯ i − y ¯ j M S E ( 1 n i + 1 n j)

They compute p-value for each 2 × C contingency table by using the chi-squared test. One can always consider using exact approaches for p-value calculation for such data . We consider this as future work.
