In semTests: Goodness-of-Fit Testing for Structural Equation Models

semTests

An R package for goodness of fit testing of structural equation models. Built on top of lavaan.

Installation

Use the following command from inside R:

# install.packages("remotes")
remotes::install_github("JonasMoss/semTests")

Usage

Call the library function, create a lavaan model, and run the pvalues function.

library("semTests")
model <- "A =~ A1+A2+A3+A4+A5;
          C =~ C1+C2+C3+C4+C5"
n <- 200
object <- lavaan::sem(model, psych::bfi[1:n, 1:10], estimator = "MLM")
pvalues(object)
#> ppeba2_trad ppeba4_trad pols_2_trad  ppeba2_rls  ppeba4_rls  pols_2_rls 
#>  0.04182486  0.04370615  0.04397064  0.04235143  0.04424139  0.04450873
