I am using Weibull AFT model to look at the effect of a dichotomous variable (adjusting for several continuous variables) on interval censored survival time. I would like to obtain expected probability of survival in the two groups of interest (defined by the two levels of the dichotomous variable) and plot them as survival curves. Can anybody help me with the options to do this in SAS. Thanks a lot.
P.S: I am using Proc lifereg to obtain the Weibull AFT model
