K1 {qtlDesign}

Calculate scores for minimum moment abberations.

Description

Calculate the MMA K1, K12, and the standardized dissimilarity score (eff1).

Usage

Kstat(genomat, type = 1)
K1(genomat)
K12(genomat)
eff1(n, nmark, s1)

Arguments

genomat

Genotype matrix.

n

Desired sample size.

type

Type of dissimilarity measure desired (first or second moment).

nmark

Number of markers.

s1

Dissimilarity score from K1 or K12.

Value

Score or standardized score based on selected marker list. K1 and K12 call Kstat with type = 1 and 2, respectively. Kstat computes the minimum moment abberation score. eff1 computes the standardized genetic dissimilarity.
