I'm trying to report mean survival time from a exponential and a Weibull distribution after adjustment of a dataset and I would like to report it from the output.

For example for the exponential distirbution the code will be something like

**Proc** **lifereg** data=temp;

model os*death(**0**)=/dist=exp;

**run**;

And from the ouput I assume that marked text of the screenshot is what I am looking for but I would like to receive the confirmation. And indeed how do I get the mean estimate form the output but using the Weibull distribution.

Thank you very much in advance.

Antonio.

To get Weibull distribution then replace the Dist=Exp with Dist=Weibull .

Thank you very much for the quick answer.

My question goes a little further, once I get the Weibull (i.e. Dist=Weibull) or Exponential (i.e. Dist=Exp) outputs how can it be derived mean survival time from them? E.g for exponential distribution, is it the estimate obtained in the Weibull scale row?
