Test of the Neutral Mutation Hypothesis

Description

This function tests the neutral mutation hypothesis with Tajima's D.

Usage

tajima.test(x)

Arguments

x	a set of DNA sequences (object of class "DNAbin").

Value

A list with three numeric values:

D	Tajima's D statistic.
Pval.normal	the p-value assuming that D follows a normal distribution with mean zero and variance one.
Pval.beta	the p-value assuming that D follows a beta distribution after rescaling on [0, 1] (Tajima, 1989).

Note

Alignment gaps in the sequences are ignored when calculating pairwise distances.
