Ordinal Log-Linear Models for Contingency Tables

Folia Oeconomica Stetinensia, 2016
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 ...

Characterization of the Maximum Probability Fixed Marginals R×C Contingency Tables

Revstat Statistical Journal, 2020
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 ...

Asymmetry Model Using Marginal Ridits for Ordinal Square Contingency Tables

Austrian Journal of Statistics, 2022
This study proposes a new marginal asymmetry model which can infer the relation between marginal ridits of row and column variables for ordinal square contingency tables. When the marginal homogeneity model does not hold, we will apply marginal asymmetry

Sparse contingency tables [PDF]

, 2021
This bachelor thesis deals with the issue of independence testing in sparse contingency tables. It defines contingency tables and describes their creation and properties. It pre- sents the most commonly used independence tests and proposes tests suitable

ESTUDIO DE ASOCIACIÓN ENTRE DROSOPHILA Y LEVADURAS USANDO EL ANÁLISIS DE DEPENDENCIA

Pesquimat, 2014
In this paper, we present the metodology of the Analysis of Dependence (ANADEP) for suggested contingency tables developed by Cordeiro (1990), using the association measures M, in the study ofstructure of association in bidimensional contingency tables.

Profile Statistics for Sparse Contingency Tables under Poisson Sampling

Austrian Journal of Statistics, 2016
Simple conditions for the inconsistency of classical likelihood ratio (LR) test in case of very sparse categorical data are given. The LR type test based on profile statistics is proposed as an alternative.

A short history of algebraic statistics [PDF]

, 2008
In algebraic statistics, computational techniques from algebraic geometry become tools to address statistical problems. This, in turn, may prompt research in algebraic geometry. The basic ideas at the core of algebraic statistics will be presented. In
