Derivations for the Weibull and log Normal are provided in the Appendix. for example my variable is a categorial variable: 0 = group A. You can also calculate median survival time for each age; for example, for a 25 year old the median survival time is solved as: These are parameters of the weibull distribution, which just equal 1 for an exponential (an exponential is a special case of weibull). 2. PREDICT has four parameters: OUTEST is the name of the data set produced with the OUTEST option. Example51.1. For example, I want it to come out something like this: PROC STATEMENT data=dataset;... RUN; Output Here. When fitting the model with LIFEREG, you must request the OUTEST data set on the PROC statement.
