Weibull Regression R. Because of technical difficulties Weibull regression model is seldom used in medical literature as compared to the semi-parametric proportional hazard model. Additionally it produces hazard ratios corresponding to the proportional hazards interpretation and event time ratios corresponding to the accelerated failure time interpretation for all covariates.
The resulting parameterization of the distributions is sometimes eg.
