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:
## load package
install.packages("equaltestMI")
library(equaltestMI)
or install the most recent version from the maintainer's GitHub repository:
# install.packages("devtools")
# library(devtools)
devtools::install_github("gabriellajg/equaltestMI", force=TRUE)
library(equaltestMI)
