SOME ISSUES ARISING FROM THE ANALYSIS OF 2×2 CONTINGENCY TABLES

Abstract

We review the 40 year old controversy over the correct analysis of 2×2 tables. It is argued that conditioning on all marginal totals is appropriate by examining the likelihood based on these margins and secondly by comparing conditional and unconditional evaluations of certain specific outcomes. Several foundational issues which naturally arise are also discussed. Copyright © 1988, Wiley Blackwell. All rights reserved
