What Does a Random Contingency Table Look Like? [PDF]
Combinatorics, probability & computing, 2008 Let R = (r1, . . ., rm) and C = (c1, . . ., cn) be positive integer vectors such that r1 + ⋯ + rm = c1 + ⋯ + cn. We consider the set Σ(R, C) of non-negative m × n integer matrices (contingency tables) with row sums R and column sums C as a finite ...

Performance Comparison of Independence Tests in Two-Way Contingency Table
Revstat Statistical Journal, 2023 Several test statistics are available for testing the independence of categorical variables from two-way contingency tables. A vast majority of published articles used the Pearson’s chi-squared test for such purposes; however, this test statistic may ...

Journal of Privacy and Confidentiality, 2012 The methodology of dierential privacy has provided a strong deni- tion of privacy which in some settings, using a mechanism of doubly-exponential noise addition, also allows for extraction of informative statistics from databases.

SVD, discrepancy, and regular structure of contingency tables
, 2013 We will use the factors obtained by correspondence analysis to find biclustering of a contingency table such that the row-column cluster pairs are regular, i.e., they have small discrepancy.
