Subgroup identification in dose-finding trials via model-based recursive partitioning [PDF]

, 2018
An important task in early phase drug development is to identify patients, which respond better or worse to an experimental treatment. While a variety of different subgroup identification methods have been developed for the situation of trials that study

Confidence bounds for nonlinear dose–response relationships

Statistics in Medicine, 2015
An important aim of drug trials is to characterize the dose–response relationship of a new compound. Such a relationship can often be described by a parametric (nonlinear) function that is monotone in dose. If such a model is fitted, it is useful to know the uncertainty of the fitted curve.

Tests for Trends in Binary Response [PDF]

, 1998
Tests for trend in binary response are especially important when analyzing animal experiments where the response in various dose--groups is of interest. Among the nonparametric tests the approach of Cochran and Armitage is the one which is most commonly ...
