Description: Statistical hypothesis testing of pattern heterogeneity
        via differences in underlying distributions across multiple
        contingency tables. Five tests are included: the comparative
        chi-squared test (Song et al. 2014) <doi:10.1093/nar/gku086>
        (Zhang et al. 2015) <doi:10.1093/nar/gkv358>, the Sharma-Song
        test (Sharma et al. 2021) <doi:10.1093/bioinformatics/btab240>,
        the heterogeneity test, the marginal-change test (Sharma et al.
        2020) <doi:10.1145/3388440.3412485>, and the strength test
        (Sharma et al. 2020) <doi:10.1145/3388440.3412485>. Under the
        null hypothesis that row and column variables are statistically
        independent and joint distributions are equal, their test
        statistics all follow an asymptotically chi-squared
        distribution. A comprehensive type analysis categorizes the
        relation among the contingency tables into type null, 0, 1, and
        2 (Sharma et al. 2020) <doi:10.1145/3388440.3412485>. They can
        identify heterogeneous patterns that differ in either the first
        order (marginal) or the second order (differential departure
        from independence). Second-order differences reveal more
        fundamental changes than first-order differences across
        heterogeneous patterns.
