This package includes a number of functions for users to examine measurement invariance via equivalence testing along with adjusted RMSEA cutoff values. In particular, a projection-based method is implemented to test the equality of latent factor means across groups without assuming the equality of intercepts.

Users can install the package from CRAN:

{r setup, message=FALSE, warning=FALSE} ## load package install.packages("equaltestMI") library(equaltestMI)

or install the most recent version from the maintainer’s GitHub repository:

{r setup2, message=FALSE, warning=FALSE} # install.packages("devtools") # library(devtools) devtools::install_github("gabriellajg/equaltestMI", force=TRUE) library(equaltestMI)
