A shortcut method is proposed using binomial coefficients to find the probabilities of all possible configurations of a 2 x 3 contingency table in a single operation. The method is especially useful ...

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 ...

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 ...
