Dichotomization of Multilevel Variables to Detect Hidden Associations
A test of independence is commonly used to determine differences (or associations) between samples in a nominal level measurement. Fisher’s exact test and Chi-square test are two of the most widely applied tests of independence used in the data analyses ...

Releasing Private Contingency Tables
Statistical agencies routinely publish aggregate data in the form of contingency tables. In this paper, we consider the problem of releasing private contingency tables so that the privacy of individual respondents in the table is preserved.

Fitting Markov property to genetic sequences
In this paper DNA sequents are modelled as discrete-state Markov chains. Statistical data is presented in contingency tables form. The generalized logit model is used to test the first-order Markov property for all coding and non-coding subsequences of ...

Performance Comparison of Independence Tests in Two-Way Contingency Table
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 ...

conting: An R Package for Bayesian Analysis of Complete and Incomplete Contingency Tables
The aim of this paper is to demonstrate the R package conting for the Bayesian analysis of complete and incomplete contingency tables using hierarchical log-linear models. This package allows a user to identify interactions between categorical factors (

Graphical Log-linear Models: Fundamental Concepts and Applications [PDF]
We present a comprehensive study of graphical log-linear models for contingency tables. High dimensional contingency tables arise in many areas such as computational biology, collection of survey and census data and others. Analysis of contingency tables

Characterization of the Maximum Probability Fixed Marginals R×C Contingency Tables
In this paper operators i[j] and [j]k are defined, whose effects on an r×c contingency table X are to subtract 1 from xij and to add 1 to xkj , respectively, so that the composition i[j]k of the two operators changes the j-th column of the contingency ...

Ordinal Log-Linear Models for Contingency Tables
A log-linear analysis is a method providing a comprehensive scheme to describe the association for categorical variables in a contingency table. The log-linear model specifies how the expected counts depend on the levels of the categorical variables for ...
