LISREL: Build the 4 basic matrices of the LISREL "all-y" representation given a set of starting values.

Description

These functions describe the structure of a path or latent variable model given a set of starting values. All fixed, free, and constrained (not yet implemented) go in them.

Usage

BETA(model)
PSI(model)
LAMBDA.Y(model)
THETA.EPSILON(model)

Arguments

model

A lavaanified model.

Value

A structural matrix with and ids attribute indicating the positions of the parameters in the lavaanified model used as input.

Examples

Run this code

data(albert)
tmp <- lvnfy(albert.model, data = albert.litho.cov, n = 107)
BE <- BETA(tmp)
PS <- PSI(tmp)
LY <- LAMBDA.Y(tmp)
TE <- THETA.EPSILON(tmp)
