Contingency's x2
WebI now have a second variable (X2), and in the same way (2x2 contingency table) have calculated the odds ratio (and risk ratio) to be greater than 1. But ... I have an expectation (from domain knowledge in my field) that when X2=0 the influence of X1 on Y may be reduced (i.e. there is an interaction between independent variables). WebThis paper describes the historical development of analytic techniques for frequency data presented as 2 x 1 or 2 x 2 contingency tables. The issues raised include: the need for a continuity correction when estimating the exceedance probability of a discrete statistic; the vulnerability of such statistics to a conservative bias when used in hypothesis testing; …
