st: Question about Baseline Hazard in Parametric Hazard Models

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. Wang
