| Subject | st: Question about Baseline Hazard in Parametric Hazard Models |
| Date | Mon, 8 Nov 2010 17:33:32 -0500 |
Dear All, I would like to specify/estimate a baseline hazard function, which is not among the distribution provided by Stata, e.g. exponential, Gompertz, in a Proportional Hazard (PH) models. For example, I want to restrict the shape of the the baseline hazard to a third degree polynomial in time, such that Lamda0(t) = exp[a0 + b1*(t) + b2*(t^2) + b3*(t^3)] Can I do that in Stata? Thank you very much in advance. Any info will be greatly appreciated. T.S.
