ZIWeibull and other ZI distributions

MarkovVaribles1 — Fri, 09 Jun 2023 00:56:07 GMT

Hello,

I am trying to fit life distribution to a time to event dataset, and JMP does not even give me the Weibull or Log-normal as an option to fit. Instead it chooses ZIFrechet as first choice.

I am using JMP 15.2.0

Thanks,

I just figured out I had a few zero time failures in the dataset and that is why I see ZI distributions!

Once I corrected the data by removing the zeros, then the fitting was fine.

Thanks
