multinomial.multcomp {RVAideMemoire}

Pairwise comparisons after an exact multinomial test

Description

Performs pairwise comparisons after a global exact multinomial test. These comparisons are performed using exact binomial tests.

Usage

multinomial.multcomp(x, p.method = "fdr")

Arguments

x

numeric vector (counts). Can also be a factor; in that case table(x) is used as counts.

p.method

method for p-values correction. See help of p.adjust.

Details

Since chi-squared and G tests are approximate tests, exact tests are preferable when the number of individuals is small (200 is a reasonable minimum).

An exact multinomial test with two groups is strictly the same than an exact binomial test.

Value

method

name of the test.

data.name

a character string giving the name(s) of the data.

p.adjust.method

method for p-values correction.

p.value

table of results.
