findIndResidualVar: Find indicator residual variances from factor loading matrix, total factor covariance, and total indicator variances.

Description

Find indicator (measurement) residual variances from a factor loading matrix, total factor covariance matrix, and total indicator variances.

Usage

findIndResidualVar(lambda, totalFactorCov, totalVarTheta = NULL, 
	kappa = NULL, covcov = NULL)

Arguments

lambda

Factor loading matrix

totalFactorCov

Total (model-implied) covariance matrix among factors.

totalVarTheta

Indicator total variances. As a default, all total variances are 1.

kappa

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

covcov

A covariance matrix among covariates

Value

A vector of indicator residual variances.
