Measures of association for contingency tables
The most general term for this type of measure is size of effect. Effect sizes allow us to make descriptive statements about samples. Traditionally, experimentalists have referred to ‘large’, ‘medium’ and ‘small’ effects, which is rather imprecise. Nonetheless, it is possible to employ statistically sound methods for comparing different sizes of effect by estimating a Gaussian confidence interv...
متن کاملBayesian Methods for Two-way Contingency Tables
In this paper, we consider Bayesian estimation and model determination for two-way contingency tables. The analysis is based on partitioning the parameter space of a saturated log-linear model into parameter subspaces identiied by considering the natural symmetries of the data. Prior distributions may then be chosen to respect invariance restrictions required by the available prior information....
متن کاملAnalysis of Two-way Contingency Tables
Pearson’s test and likelihood ratio test are two of the classical tests frequently used for testing the equality of r distributions using the data in the contingency tables. Presently we suggest an alternative test for testing the equality of distributions. It is found that the alternative test has, in general, more satisfactory levels of the acceptance probabilities under the null hypothesis, ...
متن کاملPartial Association Components in Multi-way Contingency Tables and Their Statistiical Analysis
In analyses of contingency tables made up of categorical variables, the study of relationship between the variables is usually the major objective. So far, many association measures and association models have been used to measure the association structure present in the table. Although the association measures merely determine the degree of strength of association between the study varia...
متن کاملBootstrap tests for independence in two-way ordinal contingency tables
For the analysis of an r by c contingency table having ordered row categories and ordered column categories, a bootstrap method is applied for the model-based likelihood ratio test for independence. A model-based likelihood ratio chi-square statistic and the statistic of the maximum eigenvalue of a Wishart matrix are also discussed. A simulation study is performed to compare the proposed method...
