%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.
