Description: An implementation of DuMouchel's (1999)
        <doi:10.1080/00031305.1999.10474456> Bayesian data mining
        method for the market basket problem. Calculates Empirical
        Bayes Geometric Mean (EBGM) and posterior quantile scores using
        the Gamma-Poisson Shrinker (GPS) model to find unusually large
        cell counts in large, sparse contingency tables. Can be used to
        find unusually high reporting rates of adverse events
        associated with products. In general, can be used to mine any
        database where the co-occurrence of two variables or items is
        of interest. Also calculates relative and proportional
        reporting ratios. Builds on the work of the 'PhViD' package,
        from which much of the code is derived. Some of the added
        features include stratification to adjust for confounding
        variables and data squashing to improve computational
        efficiency. Includes an implementation of the EM algorithm for
        hyperparameter estimation loosely derived from the 'mederrRank'
        package.
