WebApr 23, 2024 · You do a Fisher's exact test on each of the 6 possible pairwise comparisons (daily vs. weekly, daily vs. monthly, etc.), then apply the Bonferroni correction for multiple tests. With 6 pairwise comparisons, the P value must be less than 0.05 / 6, or 0.008, to be … If each nominal variable has just two values (a \(2\times 2\) table), use the power … WebSimilar to pairwise.wilcox.test and pairwise.t.test >, calculate pairwise comparisons of a nominal variable between group levels with corrections for multiple testing.

Performs pairwise comparisons after a comparison of proportions or after a test for independence of 2 categorical … Fisher's exact test is a statistical significance test used in the analysis of contingency tables. Although in practice it is employed when sample sizes are small, it is valid for all sample sizes. It is named after its inventor, Ronald Fisher, and is one of a class of exact tests, so called because the significance of the deviation from a null hypothesis (e.g., P-value) can be calculated exactly, rather than relying on an approximation that becomes exact in the limit as the sample size grows to infi…
