Vignette: Iterative Regression Method for Estimating Polyserial and Polychoric Correlations (under review)

You can load the package and use the function install_github

library(devtools)
install_github("panjj1125/IRME",dependencies=TRUE)

Note that this will install all the packages suggested and required to run our package. It may take a few minutes the first time, but this only needs to be done on the first use. In the future you can update to the most recent development version using the same code.

The main function to estimate the polychoric correlation is regpoly() and to estimate polyserial correlation, please use estserial(). Here is one demo:

library(IRME)
data(preschool)
IRME_cor <- polymatrix(preschool[,1:5])
