G.theo.multcomp: Pairwise comparisons after a G-test for given probabilities

Description

Performs pairwise comparisons after a global G-test for given probabilities.

Usage

G.theo.multcomp(x, p = rep(1/length(x), length(x)), p.method = "fdr")

Arguments

x

numeric vector (counts).

p

theoretical proportions.

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.
• observed
  observed counts.
• expected
  expected counts.
• p.adjust.method
  method for p-values correction.
• statistic
  statistics of each test.
• p.value2
  corrected p-values.
• p.value
  data frame of results.

Details

Since a G-test is an approximate test, an exact test is preferable when the number of individuals is small (200 is a reasonable minimum). See multinomial.theo.multcomp in that case.

Examples

counts <- c(49,30,63,59)
p.theo <- c(0.2,0.1,0.45,0.25)
G.test(counts,p=p.theo)
G.theo.multcomp(counts,p=p.theo)
