WebThis function computes the marginal homogeneity test for a k \times k k×k matrix of assignments of objects to k categories or two vectors x, y of category scores for n data objects by two raters. The statistic is distributed as \chi^2 χ2 with k-1 degrees of freedom. It can be viewed as an extension of the McNemar test to k \times k k ×k table.
