Unbiased and Efficient Estimation of Causal Treatment Effects in Cross-over Trials
Jeppe Ekstrand Halkjær Madsen, Thomas Scheike, Christian Pipper
We introduce causal inference reasoning to cross-over trials, with a focus on Thorough QT (TQT) studies. For such trials, we propose different sets of assumptions and consider thei…
Properties of a confirmatory two-stage adaptive procedure for assessing average bioequivalence
Marie Louise Østerdal, Kyle Raymond, Christian Pipper
We investigate a confirmatory two stage adaptive procedure for assessing average bioequivalence and provide some insights to its theoretical properties. Effectively, we perform Two…
A hypothesis testing framework for the ratio of means of two negative binomial distributions: classifying the efficacy of anthelmintic treatment against intestinal parasites
Matthew Denwood, Giles Innocent, Jamie Prentice +9
Over-dispersed count data typically pose a challenge to analysis using standard statistical methods, particularly when evaluating the efficacy of an intervention through the observ…
Semiparametric multi-parameter regression survival modelling
Kevin Burke, Frank Eriksson, C. B. Pipper
We consider a log-linear model for survival data, where both the location and scale parameters depend on covariates and the baseline hazard function is completely unspecified. This…
