How to output probability value from Life Distribution?

Question

Hi,

I did some reliability fitting by Life Distribution in Reliability and Survival, and I would like to output probability value from Life Distribution. Anyone knows?

Do you want the probabilities from the empirical cumulative distribution function? If so, you can get them from Distribution. Here is the CDF Plot in Distribution:

Click the red triangle next to Weight and select Save > Prob Scores. A new column appears in the data table:

I confirm the empirical CDF by plot the new scores against the original variable, Weight:

I'm not certain I'm following what you're looking for, but the method I showed previously does rely on assuming that a Weibull distribution (or whichever distribution you choose) fits the data. If you want a distribution-free output of the probability, this can be done in the Tabulate platform, using the Cumulative Probability formula in JMP. I've attached a sample data table with the script for this saved to the table.

Hi, it seemed this way can only output the probability estimates. If I would like to output the probability of the rawdata, not prbability extracted from the fitted line. Is there any quick way to output from GUI?

many thanks!
