The Contributions of William Cochran to Categorical Data Analysis.

Abstract

The paper reviews the contributions of Wm. Cochran to the analysis of categorical data, focussing on: (a) the distribution of chi-square test statistics in the presence of small expectations, and the correction for continuity. (b) the Q-test for comparing percentages in matched samples. (c) methods for strengthening chi-square-tests. (d) the Cochran test for combining results from several 2x2 tables. Some links are made between Cochran's work and recent literature on the analysis of categorical data using loglinear models. (Author)
