## stpm2

stpm2 fits flexible parametric survival models. These models use splines to model some transformation of the survial function. The most common is the $\log[-\log[S(t)]]$ link function, which fits proportional hazards models. I have added some examples and aim to add to these. Proportional hazards models Comparison with a Cox model Simple simulation study to show agreement with Cox model. Predicting hazard and survival functions (use of the timevar() option) Sensitivity analysis for the number of knots.
