cochran_qtest: [RVAideMemoire] Cochran's Q test

In aswansyahputra/sensehubr: A Tidy Approach for Sensory Analyses

Description

[This function is exported from RVAideMemoire package] Performs the Cochran's Q test for unreplicated randomized block design experiments with a binary response variable and paired data. If the p-value of the test is significant, the function performs pairwise comparisons by using the Wilcoxon sign test.

Usage

cochran_qtest(formula, data, alpha = 0.05, p.method = "fdr")

Arguments

formula	a formula of the form a ~ b | c, where a, b and c give the data values and corresponding groups and blocks, respectively. a can be a numeric vector or a factor, with only two possible values.
data	an optional data frame containing the variables in the formula formula. By default the variables are taken from environment(formula).
alpha	significance level to compute pairwise comparisons.
p.method	method for p-values correction. See help of p.adjust.

Details

If the response is a 0/1 variable, the probability of the '1' group is tested. In any other cases, the response is transformed into a factor and the probability of the second level is tested.
