rcpp_calc_Bhat2 {qtl2pleio} | R Documentation |
Estimate allele effects matrix, B hat, with Rcpp functions
Description
Estimate allele effects matrix, B hat, with Rcpp functions
Usage
rcpp_calc_Bhat2(X, Y, Sigma_inv)
Arguments
X |
dn by df block-diagonal design matrix that incorporates genetic info for two markers. Note that we can use the same marker data twice. |
Y |
dn by 1 matrix, ie, a column vector, of d phenotypes' measurements |
Sigma_inv |
dn by dn inverse covariance matrix, often composed as inverse of |
Value
a df by 1 matrix of GLS-estimated allele effects
Examples
X1 <- as.matrix(rbinom(n = 100, size = 1, prob = 1 / 2))
X <- gemma2::stagger_mats(X1, X1)
Sigma_inv <- diag(200)
Y <- runif(200)
rcpp_calc_Bhat2(X = X, Y = Y, Sigma_inv = Sigma_inv)
