In genevievelrobin/gammit: Low-Rank Interactions in Count Data with Covariates

Description

covmat

Usage

covmat(n, p, R = NULL, C = NULL, E = NULL, center = T)

Arguments

n	number of rows
p	number ofcolumns
R	nxK1 matrix of row covariates
C	nxK2 matrix of column covariates
E	(n+p)xK3 matrix of row-column covariates
center	boolean indicating whether the returned covariate matrix should be centered (for identifiability)

Value

the joint product of R and C column-binded with E, a (np)x(K1+K2+K3) matrix in order row1col1,row2col1,...,rowncol1, row1col2, row2col2,...,rowncolp

Examples

R <- matrix(rnorm(10), 5)
C <- matrix(rnorm(9), 3)
covs <- covmat(5,3,R,C)
