[R] Weibull Prediction?

response"))[1] ### Here is the mean and median of the data mean(y) median(y) ### Fitted Mean and Median from survreg fitScale<-exp(model$coef) fitShape<-1/model$scale fitScale*gamma(1 + 1/fitShape) fitScale*(log(2))^(1/fitShape) Is this done on purpose? If so does anyone know wh
