Exact and approximate methods are given for counting the number of r × c contingency tables with fixed margins. The approximate methods are extended to estimate the number of r × c × s contingency ...

A contingency table allows you to visualize the relationship between a categorical X variable and a categorical Y variable.

Tests of marginal homogeneity in a two-way contingency table given by [1], [3], and [13] do not seem to lend themselves easily to extension to the problem of m-way ...

WARNING: 50% of the cells have expected counts less than 5. (Asymptotic) Chi-Square may not be a valid test.

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 ...

R is the perfect language for creating a variety of chi-square tests, which are used to perform statistical analyses of counts of data. Here's how, with some sample code. A chi-square test (also ...
