Fisher's exact test with n x m contingency table 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 ,... Platforms: Matlab

Holm-Sidak t-test As you know, the Student t-test can be used only to compare two groups. When you have k groups you can't use a t-test for each couple because, if you have fixed alpha=0.05 for each t-test, there is a probability of k*0.05 to find a difference when it isn't (Bonferroni inequality).The Holm-Sidak...
