JSL: if - else -> find the commas?

Hi, I often face the problem that a code doesn't work because 1 out of 10 semicolons is a comma or one comma which belongs to the if block is actually missing.Is there an easy trick to make the blocks in an if-else clause more visible?

How can you add control runs to a split-plot design?

In pharmaceutical assays we often run controls on the plate which are used purely for the basis of quality control. The controls should not be part of the statistical model used to generate the DoE, and so previously I have tried to generate two DoEs (one for the main experiment, one for the controls) and merge them together. However, this is not trivial when you have a common split-plot setup, as...

Functional DOE Analysis with a mixture DOE

Does Functional DOE work when Z, Supplementory factors are mixture components? I got Generalized regression FPCA models with intercepts & negative component effects?

Midpoint control range Design Space Profiler is not transferred to Defect simulator?

Using Design Space profiler control ranges of a three component mixture and one process factor = time are specified.As shown in graph below transfer of all control ranges work fine however the midpoint of time is not taken over from the Design Space profiler? For the mixture components midpoints are transferred, why not for the process time effect?Another remark is that Defect rate (volume) of Des...

Model reduction

Hello, According to the JMP learning model for DOE analysis, non-significant terms in the model can be removed, starting with the non-significant higher order interactions (= model reduction). However, is it really that simple? Are there other things to take into considerations before removing non-significant terms? Does removing a non-significant term necessarily meant that this factor has no/min...

What functional forms are used by JMP for the desirability criteria

Hi! I have read that JMP does not use the Derringer and Suich (1980) functions to model the desirability function. How is the desirability function in JMP mathematically expressed to maximise one response and minimise another? I'd like to include this in the methods explanation of my work. Thank you in advance!

Sample size for Reliability Life Test

I have used the interval explorer for parametric reliability life test planning for sample size calculation of accelerated life test. Please can someone confirm if the sample size returned is the total sample size or sample size per stress levels? Assuming I have 3 temperature levels, do I use 75 samples per temperature level or 25?

help to get R squared predicted

Hello!I installed a script from a community response regarding the calculation of R²pred, as shown in the image below (I'm using JMP 18 pro): (link da resposta do @erich_gundlach https://community.jmp.com/t5/JMP-Add-Ins/Predicted-R-square-calculator/ta-p/39927) In PRESS, R²pred didn't appear. (Press is low because I haven't reduced the model yet, don't worry =)) I really need to show these R²pre...

Sample size calculation for accelerated life testing

I am trying to use the interval explorer for parametric reliability life test planning tool for sample size required for an ALT test but need some clarification on the following questions. 1. Is the Weibull alpha the characteristic life at stress or at use life? 2. Is the Quantile the pFail at stress or use life and how does the quantile impact the required sample size?3. Is the calculated...

How do I replace a prediction expression in a fit model with a specific expression?

Hi, I am completing a DOE and I have ran a fit model using the JMP software to define a design space based on desirability of certain variables, however one of the desirability variables is a simple ratio of two of the construct model effects, however when running the model, the model is defining its own prediction expression for this variable rather than using the formula in the data table. Does ...

How does AICc criterion and Combined rules interact in Stepwise Fit Platform?

As an entry-level user of JMP but with a bit of statistical knowledge. I encountered with a problem when trying to use the stepwise fit platform to develope a regression model for my DoE dataset.

I read the JMP help book and understand how combined rule applied to p-value based stepwise regression (a joint F-test and another partial F-test of interaction effect when added precedent main effects). ...
