Analysis of Contingency Tables Bayesian Analysis of Contingency Tables
The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables. Given independent samples of two binomial distributions and taking a mixed prio...
متن کاملOn Cluster Analysis Based on Contingency Tables
In _ Zytkow and Zembowicz (1993), a system for cluster analysis, based on two-way contingency tables, has been proposed. In its original form, the system is con ned to categorical and discrete multivariate data. The aim is to build a classi cation tree when, at each level of the tree, only binary splits are allowed. Within a one-level taxonomy formation, a systematic search is performed for pai...
متن کاملMaypole: Visualisating Contingency Tables
Data Visualisation is a powerful tool in modern computing. It allows ease of navigation of large information spaces and it is invaluable in communicating complex ideas. As the volume of data stored by organisations continues to increase, Data Visualisation can reduce mountains of data to visually insightful representations, which can aid decision making, increase productivity, and in some cases...
متن کاملReleasing Private Contingency Tables
Statistical agencies such as the US Census Bureau routinely release aggregate statistics about the general population. These statistics are often reported in the form of contingency tables. A 2-dimensional contingency table is an (m + 1) × (n + 1) matrix over two attributes that are binned into m rows and n columns. For instance, the attributes could be Age binned into buckets of length 10 and ...
متن کاملSampling contingency tables
Given positive integers r1; r2; : : : rm and c1; c2; : : : cn, let I(r; c) be the set ofm n arrays with nonnegative integer entries and row sums r1; r2; : : : rm respectively and column sums c1; c2; : : : cn respectively. Elements of I(r; c) are called contingency tables with these row and column sums. We consider two related problems on contingency tables. Given r1; r2; : : : rm and c1; c2; : ...
