  • Random coding values

    Sometimes when setting up a DoE in JMP, the +1, -1 coding  is joined by seemingly random additional values, as in the -0.3 value in the snip below. I assume such a value is genuine and not a mistake.  Can anyone explain what such a value means?

  • 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?

  • Functional Data Analyses returning DoE-factor (FDOE?)

    Is it possible to do Functional Data Analyses like FPCA where the components reflect DoE-factors? (like in ASCA). It seems that FDOE profiler does something similar. Where can I fin it in JMP 18-pro?

  • 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...

  • Lin's Concordance Correlation Coefficient

    Hi All Is there a procedure in JMP that computes  Lin's Concordance Correlation Coefficient?  The concordance correlation coefficient (Lin, 1989) evaluates the degree to which pairs of observations fall on the 45° line through the origin. Lin L.I-K (1989) A concordance correlation coefficient to evaluate reproducibility. Biometrics 45:255-268 Cheers Vince

  • 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). ...
