Is your feature request related to a problem? Please describe.
Right now, only the Weibull accelerated failure time model is supported. If we implement the generalized-gamma model, then I will be able to implement various other distributions automatically (weibull, exponential, gamma, inverse-weibull, inverse-gamma). This could replace much of the survival.py estimating equations.
Describe the solution you'd like
Implement the generalized-gamma AFT model.
Describe alternatives you've considered
Bespoke estimating equations, which would be burdensome to implement and upkeep.
