How to set confidence interval's method to likelihood instead of Wald for the Distribution Profiler in 'Fit Life by X'

Hi everyone, This seems to be a simple question, but I cannot find the solution. In Analyze toolbar > Reliability and Survival > Fit Life by X, there is a distribution profiler. My problem is that the confidence intervals (CIs) shown here are using Wald's method, even when I selected the likelihood as the preferred CI method. Unfortunately, I also cannot find the button to change from Wald to like...

Splitting survival curve

JMP 17Dear all, I would appreciate your help with the following issue. I have a database of ca. 300 individuals split into 3 groups. The goal is to assess their survival over time. I have generated a Kaplan-Meier survival curve (max follow-up time 35 years) and log-rank is showing p<.05. Now I would like to split it and look into whether survival rates between those 3 groups differ at different ti...

How to output probability value from Life Distribution?

Hi, I did some reliability fitting by Life Distribution in Reliability and Survival, and I would like to output probability value from Life Distribution. Anyone knows?

Classifying audio files

Is there a way to process raw audio files with or without metadata? Having a microphone installed to detect noise is a cheap way to protect equipment and personnel from damage. However, it would be much more efficient if the sound is classified (as being false alarm, object loose etc). Can a model be trained in JMP for that purpose?

Why are my fit models showing different factor significance? In "model 1", Random Block is a Random Effect rather than a Fixed Effect, whereas "model 2" lists all the factors as Fixed Effects.

When I clicked Fit Model, "model 1" popped up, including "Random Block & Random" as a factor, which means "Random Block" is a Random rather than Fixed Effect. However, When I run "model 2" with just "Random Block" as a factor, everything becomes less efficient. Which is more correct and why? Also, I'm used to the Model 2 output, in which I can click on Scaled Estimates. And I was taught at a JMP t...

What exactly is "Location relationship" in reliability tool? (fit life by X)

Hello,I'm using JMPpro for reliability data analysis.I understand that "fit life by X" tool can be used for ALT data analysis and the "relationship" seems to show an accelerated test condition-lifetime relationship(Arrhenius, Linear etc.). What is "Location" and "no effect"? JMP help document says: Location means that μ is different for every level of XDoes this mean that it is used when there is ...

Difference in Risk Ratio stats between JMP 15 & JMP 16?

OK, have I got a question for y'all! I'm teaching survival analysis and looking at Proportional Hazards Fit and Risk Ratios. In JMP 15 I'm getting a Prob>Chisq of <.0001 for my risk ratios (yes, it's an odd dataset where the differences in survival are rather large) with understandable 95% confidence limits. I've assumed this is testing the Ho that the risk ratio is not significantly different ...

Friedman post hoc analysis

Hello, I am trying to do a matched sample analysis across three different factors. I wanted to:1. Confirm that my sample would be what I pick for 'Block" when I do Fit Y by X when running Friedman's test2. Is there a post hoc analysis in JMP that I can use? I dont see Nemenyi or Conover as an optionThanks for your time.
