Description: The Upsilon test assesses association among
 categorical variables against the null hypothesis of
 independence (Luo 2021 MS thesis; ProQuest Publication
 No. 28649813). While promoting dominant function patterns,
 it demotes non-dominant function patterns. It is robust
 to low expected count---continuity correction
 like Yates's seems unnecessary. Using a common null
 population following a uniform distribution, contingency
 tables are comparable by statistical significance---not
 the case for most association tests defining a varying
 null population by tensor product of observed marginals.
 Although Pearson's chi-squared test, Fisher's exact test,
 and Woolf's G-test (related to mutual information) are
 useful in some contexts, the Upsilon test appeals to
 ranking association patterns not necessarily following
 same marginal distributions, such as in count data
 from DNA and RNA sequencing---a rapidly expanding frontier
 in modern science.
