This function tests, for a series of loci, the hypothesis that
genotype frequencies follow the Hardy--Weinberg equilibrium.
Usage
hw.test(x, B = 1000)
Arguments
x
an object of class "loci".
B
the number of replicates for the Monte Carlo procedure.
Value
a matrix with three or four columns with the $\chi^2$-value,
the number of degrees of freedom, associated P-value, and
possibly the P-value from the Monte Carlo test. The rows of
this matrix are the different loci in x.
Details
This test can be performed with any level of ploidy. Two versions
of the test are available: the classical $\chi^2$-test based
on the expected genotype frequencies calculated from the allelic
frequencies, and an exact test based on Monte Carlo permutations of
alleles. The latter version is available only for diploids. Set
B = 0 if you want to skip the latter test.
