Calculate heritability of pairwise differences using variance parameters

H2_Delta_parameters.Rd

Compute broad-sense heritability of differences using the variance of differences between two BLUPs/BLUEs

Usage

H2_Delta_parameters(delta_g, delta_pev, type = c("BLUP", "BLUE"))

Arguments

delta_g

Numeric. Genotypic variance-covariance matrix.

delta_pev

Matrix. Variance of pairwise differences among BLUES or BLUPs

type

Character. Either BLUES or BLUPS used to compute the variance of pairwise differences.

Value

Matrix of pairwise heritability of differences among BLUES or BLUPs

Details

See H2_Delta() and reference for full derivation and equation for heritability Delta
