scavar: Scaling Item Variances

In hvongbg/bindabox: Toolbox for fixed-links modelling

Scaling Item Variances

Description

Function scales variances of each item in model. To get scaled variances for latent variables, run the original model again, but fix each item with the scaled variance provided by this function.

Usage

scavar(LambdaMatrix, col)

Arguments

LambdaMatrix	get LambdaMatrix directly from your lavaan object (fit_model <- sem(model, ...)). LambdaMatrix <- lavInspect(fit_model, what = "std.all")
col	select column for which latent variable the variances should be scaled. scavar(LambdaMatrix$lambda, 2)

Details

Scaling variances makes values comparable.

Value

List of the scaled varaince for each item is returned.
