Abstract: Many new statistical models may enjoy better interpretability and numerical stability than traditional models in survival data analysis. Specifically, the threshold regression (TR) technique based on the inverse Gaussian distribution is a useful alternative to the Cox proportional hazards model to analyse lifetime data. In this article we consider a semi-parametric modelling approach for TR and contribute implementational and theoretical details for model fitting and statistical inferences. Extensive simulations are carried out to examine the finite sample performance of the parametric and non-parametric estimates. A real example is analysed to illustrate our methods, along with a careful diagnosis of model assumptions. © 2011 The Authors. Statistica Neerlandica © 2011 VVS.
