Compute broad-sense heritability of differences
using the variance of differences between two BLUPs/BLUEs
Usage
h2_Delta_parameters(G_g, vd_matrix, type)
H2_Delta_parameters(vc_g, vd_matrix, type)
Arguments
- vc_g
Numeric. Genotype variance component
- vd_matrix
Matrix. Variance of pairwise differences among BLUES or BLUPs
- type
Character. Either BLUES or BLUPS used to compute the variance of pairwise differences.
- G_g
Numeric. Genotypic variance-covariance matrix.
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
