• 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...

  HiI need to compute the intraclass correlation for 2 readers who measured the same subject once each. I have rows of subjects with a column for each reader. It does not seem possible to do this with the MSA tool, which gives me an error when I try to use it (not enough information to compute standard deviation). SPSS does this with essentially one click (Reliability tool). Am I missing something? ...

• Find Reliability from bimodal data

  Hello, I am currently analyzing a few data sets which seem to have a bimodal distribution. I am currently using the 'Life Distribution' under 'Reliability and Survival' but the distributions that best fit are Log Generalized Gamma, Generalized Gamma, Threshold Weibull, Frechet, etc. which don't really make much sense for the given data and where it comes from. Below is a snapshot of what I am tryi...
