In gekim0519/tidyfunfun:

Description

Internal function used compute the products '(X otimes Theta)^t (I otimes Sigma^-1) (X otimes Theta)' and '(X otimes Theta)^t (I otimes Sigma^-1) (y)' in cross-sectional VB algorithm and Gibbs sampler

Usage

Xt_siginv_X(tx, siginv, y = NULL)

Arguments

tx	transpose of the X design matrix
siginv	inverse variance matrix
y	outcome matrix. if NULL, function computes first product; if not, function computes second product.
