Find the threshold (concentration) that provide the best&nbsp;dichotomization.</P> <P>&nbsp;</P> <P>Thanks.</P> Fri, 09 Jun 2023 00:42:23 GMT shylxy 2023-06-09T00:42:23Z https://community.jmp.com/t5/Discussions/Cox-proportional-hazards-model-for-threshold/m-p/439647#M68807 <P>Hi,</P> <P>Can JMP run the following analysis?</P> <P>A Cox proportional hazards model for each threshold (continuous drug concentration data) was fitted to the data, and the threshold that provided the best fit to the data (i.e., lowest Akaike information criterion [AIC]) was selected as the threshold for dichotomization (time to event, PFS).

Would you please elaborate? E.g.</P> <OL> <LI>A published journal paper.</LI> <LI>A description of the model.</LI> <LI>A description of your data.</LI> </OL> Mon, 29 Nov 2021 13:24:59 GMT https://community.jmp.com/t5/Discussions/Cox-proportional-hazards-model-for-threshold/m-p/440460#M68891 peng_liu 2021-11-29T13:24:59Z
