• Question about Kaplan Meier survival curves.

  Hello, I'm very new to JMP software. I'm trying to generate Kaplan Meier survival curve for my research. So far, I made my data set like this (If I made a mistake about the below table for Kaplan Meier, let me know):Time (day)DiedCencor00012.67022031040.3305005241 After that, I used the Survival platform (Y=months, Censor=censor, and Freq=died). The result started with day 1. But I want to get thi...

• Kaplan-Meier Analysis

  Hi everyone, I would like to conduct a Kaplan-Meier Survivorship analysis with JMP (version 15.2.1). I want the confidence intervals to be calculated with the Greenwood log-log approach. But I am not sure which formula JMP uses and I cannot find anything about that.Does anyone know if the upper and lower 95% values in the JMP survival analysis is calculated with the Greenwood log-log approach? If ...

• distribution parameters mismatch between Competing Risk Mixture and SubSample in Life Data platform

  Hi All,I use Life Distribution platform from Reliability and Survival to fit distribution to reliability results. To distinguish between failure causes I used 2 Weibull distributions in Competing Risk Mixture of Life Distribution platform (see graphs below and attached file). Portion 1 value (marked with yellow) from the Competing Risk Mixture report species part of reliability results related to ...

• Reliability analysis: many points outside confidence band

  Hi I have a dataset that has failures at cycles: 10, 11, 17, 28, 26, 10, 10, 1, 1, 1,1244, 1100. 187678 censored at cycle 30 (test stopped). 162834 censored at cycle 300 and 13313 censored at 3000.When I use JMP's life distribution to analyze this data, I get strange plot with most the censored points outside the confidence band.I have not used JMP for a while and use JMP 15. Is there anything wro...

• Cox proportional hazards model for threshold

  Hi, Can JMP run the following analysis? 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). Find the threshold (concentration) that provide the best dichotomiza...
