The geometry of statistical models for two-way contingency tables with fixed odds ratios

Risultato della ricerca: Contributo su rivista › Articolo in rivista › peer review

Abstract

We study the geometric structure of the statistical models for two-by-two contingency tables. One or two odds ratios are fixed and the corresponding models are shown to be a portion of a ruled quadratic surface or a segment. Some pointers to the general case of two-way contingency tables are also given and an application to case-control studies is presented.
