Implementing Horn's parallel analysis for principal component analysis and factor analysis
Abstract. I present paran, an implementation of Horn’s parallel analysis criteria
for factor or component retention in common factor analysis or principal component
analysis in Stata. The command permits classical parallel analysis and more
recent extensions to it for the pca and factor commands. paran provides a needed
extension to Stata’s built-in factor- and component-retention criteria.
