Can you share the other tables in this report? For example, what are the parameter estimates? What are the diagnostics?</P> Sat, 08 Jul 2023 14:01:07 GMT Mark_Bailey 2023-07-08T14:01:07Z https://community.jmp.com/t5/Discussions/Nominal-logistic-fit-effects-summary-and-zero-p-vaues/m-p/656636#M84567 <P>In the effect summary of the logistic fit, I expected to see a logworth value for a p-value that appears to be zero. But 3 out of 4 parameters with p-values of zero did not have a logworth value. So I check the p-value with the scientific notation format and the 3 parameters without a log worth value were actual zero not a very small number close to zero.&nbsp; The RSquare (U) for this model is 1. I'm not sure what to make of this.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="LittleLeavitt_1-1688762395513.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/54497i7C22C669D4701A8B/image-size/medium?v=v2&amp;px=400" role="button" title="LittleLeavitt_1-1688762395513.png" alt="LittleLeavitt_1-1688762395513.png" /></span></P><P>&nbsp;</P><P>&nbsp;</P> Fri, 07 Jul 2023 20:48:19 GMT https://community.jmp.com/t5/Discussions/Nominal-logistic-fit-effects-summary-and-zero-p-vaues/m-p/656636#M84567 LittleL 2023-07-07T20:48:19Z https://community.jmp.com/t5/Discussions/Nominal-logistic-fit-effects-summary-and-zero-p-vaues/m-p/656719#M84572 <P>You might have mis-specified the model.
