semTests

CRAN_Status_Badge R-CMD-check Project Status: Active – The project has reached a stable, usable state and is being actively developed.

An R package for goodness of fit testing of structural equation models. Built on top of lavaan. Implements the p-values of (Foldnes, Moss, Grønneberg, 2024).

Installation¨

Either install from CRAN,

install.packages("semTests")

Or install the development version using the following command 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)
