multinomial.multcomp: 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).

p.method

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

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.

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.
