What is Fisher's exact test? Fisher’s exact test is a statistical hypothesis test used to assess the association between two binary variables in a contingency table and is particularly useful when ...
sorts the data in descending order so that the first table cell contains the frequency of positive exposure and positive response computes chi-square tests, exact Pearson chi-square test, and Fisher's ...
For the one-response, two-factor design with categorical data, Gart (1972) proposed a statistic to test the hypothesis of zero second-order interaction. It can be shown that unconditionally the ...
computes asymptotic tests for Somers' D(C|R). The Cochran-Armitage test checks for trend in binomial proportions across levels of a single factor. Use this test for a contingency table with a ...
Assuming a multinomial sampling model, prior distributions are developed which can accept prior information about symmetry and independence in a two-way contingency table. Bayesian estimates for the ...
