matW: Calculate matrix W

In GEInfo: Gene-Environment Interaction Analysis Incorporating Prior Information

Description

Calculate observed matrix W for all G variables and G-E interactions. Denote Wj as the n x (q+1) sub-matrix of W corresponding the jth G variable. The first column of Wj is the observation vector of the jth G variable, and the rest q columns of Wj are observations of G-E interactions.

Usage

matW(E, G)

Arguments

E	Observed matrix of E variables, of dimension n x q.
G	Observed matrix of G variables, of dimensions n x p.

Value

A matrix of dimension n x [p(q+1)].

Examples

n <- 30; q <- 3; p <- 5;
E <- MASS::mvrnorm (n, rep (0, q), diag (q))
G <- MASS::mvrnorm (n, rep (0, p), diag (p))
W <- matW (E, G)
