JMP reliability data

Hello JMP community,

I have some reliability data to analyse. When I use JMP Analyse >> reliability and survival >> life distribution, after I entered Y, time to Event and Censor, I selected Weibull fitting and get all statistics. How can I get the R2 for the Weibull fitting?

Reliability Analysis

Re: JMP reliability data

When you say R2, I think you mean R-squared from least squares regression.

Life Distribution uses maximum likelihood estimation, which is the proper method compared to least squares.

So, you won't find R2.

Hi @ClipShift : To follow up @peng_liu , pretty good article here comparing the two methods.
