The Odds Ratio and Aggregate Data: The 2×2 Contingency Table
نویسندگان
چکیده
The odds ratio remains one of the simplest of measures for quantifying the association structure between two dichotomous variables. Its use is especially applicable when the cell values of a 2× 2 contingency table are known. However, there are cases where this information is not known. This may be due to reasons of confidentiality or because the data was not collected at the time of the study. Therefore one must resort to considering other means of quantifying the association between the variables. One strategy is to consider the aggregate association index (AAI) proposed by [1]. This paper will explore the characteristics of the AAI when considering the odds ratio of the 2× 2 contingency table.

3 Algebraic geometry of 2 × 2 contingency tables
Contingency tables represent the joint distribution of categorical variables. In this chapter we use modern algebraic geometry to update the geometric representation of 2 × 2 contingency tables first explored in (Fienberg 1968) and (Fienberg and Gilbert 1970). Then we use this geometry for a series of new ends including various characterizations of the joint distribution in terms of combination...
متن کاملThe Geometry of Statistical Models for Two-way Contingency Tables with Fixed Odds Ratios
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.
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 کاملA Fourfold Display for 2 by 2 by k Tables
This paper describes the fourfold display, a graphic designed to display the frequencies in a 2 × 2 × k contingency table. In this display the frequency in each cell is shown by a quarter circle, whose area is proportional to the cell count in a given 2 × 2 layer, in a way that depicts the odds ratios for k strata. Confidence rings for the odds ratio can be superimposed to provide a visual test...
متن کاملA reformulation of the aggregate association index using the odds ratio
Since its inception in the 1950s the odds ratio has become one of the most simple and popular measures available for analysing the association between two dichotomous variables. Since the direction andmagnitude of the association can be captured in such a simple measure, its impact has been felt throughout much of scientific research, in particular in epidemiology and clinical trials. Despite t...
