Description

This function estimates the model parameters under the null model when there is no region genotypes effect, for the VCC methods

Usage

1
Estim.H0.VCC(y, X, S, U)

Arguments

y

Vector of phenotype values

X

A matrix of covariates, including intercept.

S

Matrix obtained from spectral decomposition of the relationship matrix: Φ = U S U^T.

U

Matrix obtained from spectral decomposition of the relationship matrix: Φ = U S U^T.

Value

a list of:

  • h.hat: estimate of the (narrow sense) heritability

  • gam.hat: a vector of estimates of fixed effects of the covariates (if there are any).

  • residuals: residuals from adjusting the null model with only covariates in the model.
