SachaEpskamp/polyCov: Estimate polychoric correlations and covariances.

This is a very small package with only one function, polyCov(), designed to simplify the implementation of ordinal multigroup factor analysis in R. This function can be used to estimate a polychoric (or tetrachoric) correlation matrix assuming standardized latent items. If thresholds are given, it estimates polychoric covariances, means and variances.
