Diffusion piecewise exponential models for survival extrapolation using Piecewise Deterministic Monte Carlo
Luke Hardcastle, Samuel Livingstone, Gianluca Baio
The piecewise exponential model is a flexible non-parametric approach for time-to-event data, but extrapolation beyond final observation times typically relies on random walk prior…

Averaging polyhazard models using Piecewise deterministic Monte Carlo with applications to data with long-term survivors
Luke Hardcastle, Samuel Livingstone, Gianluca Baio
Polyhazard models are a class of flexible parametric models for modelling survival over extended time horizons. Their additive hazard structure allows for flexible, non-proportiona…
