Description: paran is an implementation of Horn's technique for
        numerically and graphically evaluating the components or
        factors retained in a principle components analysis (PCA) or
        common factor analysis (FA). Horn's method contrasts
        eigenvalues produced through a PCA or FA on a number of random
        data sets of uncorrelated variables with the same number of
        variables and observations as the experimental or observational
        data set to produce eigenvalues for components or factors that
        are adjusted for the sample error-induced inflation. Components
        with adjusted eigenvalues greater than one are retained. paran
        may also be used to conduct parallel analysis following
        Glorfeld's (1995) suggestions to reduce the likelihood of
        over-retention.
