Test Of Homogeneity For Umbrella Alternatives In Dose-Response Relationship For Poisson Variables
This article concerns the testing and estimation of a dose-response effect in medical studies. We study the statistical test of homogeneity against umbrella alternatives in a sequence of Poisson distributions associated with an ordered dose variable. We propose a test similar to Cochran-Armitageās trend test and study the asymptotic null ā¦
