findFactorMean: Find factor total means from regression coefficient matrix and factor intercept

Description

Find factor total means from regression coefficient matrix and factor intercepts for latent variable models. In the path analysis model, this function will find indicator total means from regression coefficient and indicator intercept.

Usage

findFactorMean(beta, alpha = NULL, gamma = NULL, covmean = NULL)

Value

A vector of factor (indicator) total means

Arguments

beta

Regression coefficient matrix among factors

alpha

Factor (indicator) intercept. The default is that all factor intercepts are 0.

gamma

Regression coefficient matrix from covariates (column) to factors (rows)

covmean

A vector of covariate means.
