WebIn Statistical Methods of Cancer Research; Volume 1 - The analysis of case-control studies the authors Breslow and Day derive a statistic to test for the homogeneity of combining strata into an odds ratio (equation 4.30). Given the value of the statistic, the test determines if it is appropriate to combine strata together and compute a single odds ratio. WebHere, the underlying question of the Breslow-Day test can be answered by investigating whether an interaction term with the strata variable is necessary (e.g. using a likelihood …

Weblarge). This makes the test reasonably stable for sparse data, more so than for the unconditional test (Liang and Self 1985). One major disadvantage of the conditional test is that it is computationally burdensome except when the sample size is small, and Breslow and Day suggested re-placing the conditional MLE with the Mantel-Haenszel

Perhaps the most useful test is a test of the hypothesis that the X-Y association differs across levels of Z, known as the Brelow-Day test (Breslow & Day, 1980). Later modified by Tarone (1985), it is sometimes referred to as the Breslow-Day-Tarone test. If there is no difference across levels of Z, the X-Y relationship is ...
WebThis is performed by including an interaction term between study and treatment, and then applying either a Wald test, a score test, or the Likelihood ratio test for its significance (Agresti, 2002). A method that studies the heterogeneity of the odds ratio directly is the Breslow–Day test adjusted by Tarone ( 1985 ).
