WC_FST_FiniteSample_Diploids_2Alleles_NoCorr: FSTNoCorr calculation for biallelic diploid data

In whitlock/OutFLANK: Fst outliers with trimming

Description

Calculates FST without correction for local sample sizes, for diploid biallelic data. This is necessary for using OutFLANK, which depends on these uncorrected values for reliable function. (Otherwise, sampling corrections can sometimes cause negative estimates of FST.)

Usage

WC_FST_FiniteSample_Diploids_2Alleles_NoCorr(Sample_Mat)

Arguments

Sample_Mat

This is an array with a row for each population, and three values per row: Number of Homozygotes of one type, number of heterozygotes, number of homozygotes of other type.

Value

Returns a list of values related to FST:

• He: the expected heterozygosity of the locus

• FSTNoCorr: Fst (without sample size correction)

• T1NoCorr: The numerator of the uncorrected sample size correction (similar to Weir and Cockerham 1984)

• T2NoCorr: The denominator of the uncorrected sample size correction
