Dear Helpers:

If you know how to fit a Weibull model using R, you are my savior for my project. The hazard ramda is specified as t^alpha * (1+a*dose*exp(-b*dose)). Or, can we modify the Cox model to capture the proportional part above? Here t is the survial time, dose is a subject received in a exposed group.

Thank you a lot.
