Bayesian Power Prior Design for Survival Outcomes

Bayesian power/type I error calculation and model fitting using the power prior and the normalized power prior for time-to-event endpoints. The proportional hazards model with piecewise constant hazard (piecewise exponential) is implemented. The methodology and examples of applying the package are detailed in . The Bayesian clinical trial design methodology is described in Chen et al. (2011) , and Psioda and Ibrahim (2019) . The proportional hazards model with piecewise constant hazard is detailed in Ibrahim et al. (2001) .
