• Survival analysis model generation and performance evaluation

  I want to predict mortality over 15 years in a cohort of patients. Data is right censored, with a  mortality of 7% in 15 years of observation. The data set to derive a prediction model is about 3,500 subjects and 2,000 for external validation. I ran a Cox proportional hazard model, where I identified significant predictors and their Risk ratios, and a parametric survival analysis where significant...

• Sample size calculation for TOST

  Hi everyone! Context: I have a process A which is my reference, and I developped a process B which I want to assess its comparability to process A. To do so, I plan to use a TOST (equivalence test) using the process A's 3xSTD (standard deviation) as a treshold. Now, I want to know how many time should I repeat process B to be sure to be able to detect such variation (knowing that a run is a signif...

• Classification of Variables

  Hello I am very new to JMP but I would like to check about for validation of chromatographic methods what the correct categorization of the variables should be:For instance UV detector wavelength (would this be discrete numeric?)Column Temperature (continuous)Flow Rate (continuous)Mobile Phase A Buffer concentration (continuous)pH of Mobile Phase A (continuous) Many Thanks James

• JMP Pro, Dantzig selector: how do I improve computational time

   Hello JMP community members. Concerning the use of the Dantzig selector on big and sparse datasets.I wondered what features would be at disposal to tune the computational time.Right now it takes about 40 minutes to get a result back for a problem with 380 rows and 149 non-singular parameters. This makes me wonder about the options available to tweak the computation time. I was thinking about redu...
