pairwiseMcnemar: Pairwise McNemar and related tests for Cochran Q test post-hoc

Description

Conducts pairwise McNemar, exact, and permutation tests as a post-hoc to Cochran Q test.

Usage

pairwiseMcnemar(x, g, block, test = "exact", method = "fdr", digits = 3, correct = FALSE)

Arguments

x

The response variable.

g

The grouping variable.

block

The blocking variable.

test

If "exact", conducts an exact test of symmetry analogous to a McNemar test. If "mcnemar", conducts a McNemar test of symmetry. If "permutation", conducts a permutation test analogous to a McNemar test.

method

The method for adjusting multiple p-values. See p.adjust.

digits

The number of significant digits in the output.

correct

If TRUE, applies a continuity correction for the McNemar test.

Value

A list containing: a data frame of results of the global test; a data frame of results of the pairwise results; and a data frame mentioning the p-value adjustment method.

Details

The component tables for the pairwise tests must be of size 2 x 2.
