ZIWeibull and other ZI distributions

Created: Oct 20, 2022 10:19 AM  |  Last Modified: Jun 8, 2023 5:56 PM (492 views)

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
