Inference for changepoint survival models
Roxane Duroux, John O'Quigley
We consider a non-proportional hazards model where the regression coefficient is not constant but piecewise constant. Following Andersen and Gill (1982), we know that a knowledge o…
Conditional survival given covariates and marginal survival
Roxane Duroux, Cécile Chauvel, John O'Quigley
Assuming some regression model, it is common to study the conditional distribution of survival given covariates. Here, we consider the impact of further conditioning, specifically…
Survival model construction guided by fit and predictive strength
Cécile Chauvel, John O'Quigley
We describe a unified framework within which we can build survival models. The motivation for this work comes from a study on the prediction of relapse among breast cancer patients…
Continual Reassessment and Related Dose-Finding Designs
John O'Quigley, Mark Conaway
During the last twenty years there have been considerable methodological developments in the design and analysis of Phase 1, Phase 2 and Phase 1/2 dose-finding studies. Many of the…
