initGroup.lvm: Reshape information for building the V matrices

In bozenne/lava.penalty: Penalized Latent Variable Models

Description

Return matrices containg the endogenous, exogenous and group index corresponding to each penlized link. Take care of categorical variables.

Usage

initGroup.lvm(x, links, group)

Arguments

x	a lvm-object
links	the name of the penalized links
group	define the groups of the penalty

Examples

## no category
m <- lvm(Y~X1+X2+X3)
dt <- initGroup.lvm(m, links = c("Y~X1","Y~X2"))
dt

## categories
categorical(m, labels = c("A","B","C")) <- "X1"
dt <- initGroup.lvm(m, links = c("Y~X1","Y~X2"))
dt
categorical(m, K=2, labels = 1:2) <- "X2"
dt <- initGroup.lvm(m, links = c("Y~X1","Y~X2"))
dt

regression(m) <- Z~X1+X3+X5+eta
latent(m) <- ~eta
dt <- initGroup.lvm(m, links = c("Y~X1","Y~X2","Z~X1"))
dt
