Description: A set of functions to perform parallel analysis for
        principal components analysis intended mainly for large data
        sets. It performs a parallel analysis of continuous, ordered
        (including dichotomous/binary as a special case) or mixed type
        of data associated with a principal components analysis.
        Polychoric correlations among ordered variables, Pearson
        correlations among continuous variables and polyserial
        correlation between mixed type variables (one ordered and one
        continuous) are used. Whenever the use of polyserial or
        polychoric correlations yields a non positive definite
        correlation matrix, the resulting matrix is transformed into
        the nearest positive definite matrix. For details on the GSL
