Calculate Oakey's heritability using variance parameters — H2_Oakey_parameters • heritable

Rather than providing a model object, supply the necessary components to compute this heritability measure.

Usage

H2_Oakey_parameters(Gg_inv, C_gg)

Arguments

Gg_inv: The inverse of the genotypic variance-covariance matrix.
C_gg: Prediction error variance matrix associated with the genotype effects.

Value

Numeric value

Examples

Gg_inv = diag(1/0.15, 3, 3)
C_gg <- matrix(
  c(
    0.08, 0.01, 0.00,
    0.01, 0.07, 0.01,
    0.00, 0.01, 0.09
  ),
  nrow = 3, byrow = TRUE
)
H2_Oakey_parameters(Gg_inv, C_gg)
