Description: Estimation methods for zero-inflated Poisson factor
        analysis (ZIPFA) on sparse data. It provides estimates of
        coefficients in a new type of zero-inflated regression. It
        provides a cross-validation method to determine the potential
        rank of the data in the ZIPFA and conducts zero-inflated
        Poisson factor analysis based on the determined rank.
