RMST in survival analysis

[COMPAREMISSING]

I need to calculate the restricted mean survival time (RMST) for several milestones.

Someone can said to me if there is a simple way to do it in SAS? Or if exist a macro to do it?

Thanks in advance,

same question here.

After I find the best model based on AIC ( weibull, exp, gamma....), how could  I  use use the output estimated parameters to calculate the restricted mean survival time  given a time point ? 

Thanks !
