findFactorIntercept: Find factor intercept from regression coefficient matrix and...

In simsem: SIMulated Structural Equation Modeling

Description

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

Usage

findFactorIntercept(beta, factorMean = NULL, gamma = NULL, covmean = NULL)

Arguments

beta	Regression coefficient matrix among factors
factorMean	A vector of total (model-implied) factor (indicator) means. The default is that all total factor means are 0.
gamma	Regression coefficient matrix from covariates (column) to factors (rows)
covmean	A vector of covariate means.

Value

A vector of factor (indicator) intercepts
