  • Non normal and unequal variance

    Hello everyone,

    I am analyzing a dataset with three treatment factors. The data satisfy the normality assumption but violate the assumption of homogeneity of variance. I understand that Welch’s ANOVA may not be appropriate because I want to evaluate the main effects of each factor as well as their interactions.

    In another scenario, the data violate both the normality and homogeneity of variance assu...

  • Problem Bayesian Optimisation

    In an earlier R&D study I sucessfully used a 4 factor mixture DOE (3 mixture factors and one 3-level categorical "Isomer" effect) to find optimal settings for a chemical formulation with three quality attributes Y1, Y2 and Y3. I used the case in a DOE course and used simulation formulas to compute the responses Y123. Good models are obtained and optimization was straightforward and OK, see "ANALYS...

  • Logistic Regression Diagnostics in Generalized Linear Model with Firth Bias Adjustment

    I am looking for guidance on how to perform diagnostics (model fit, model form, assumptions, outliers) of logistic regression models created using the fit model generalized linear model personality. The generalized linear model personality must be used in this case because the data has small sample sizes and complete separation. The only diagnostic plots available in the generalized linear model p...

  • Unexpected number of cases as result of a concatenation operation.

    I have extracted from 2025 and 2024  Census SIPP files  the records for householders in the month of December.  There are 13910 records in 2025 and 15,877 in 2024.   I am using the Catenate command to link the two files, not a merge or update command.  I am creating a new file with a column indicating source. I get a file of 15,877 records, not 33000.  I get no source column.  Since these records ...

  • PINNs in JMP?

    Hello All,   Although this question is a bit more directed at JMP employees, other users might have additional information as well.   I'm curious if JMP plans to implement any physics-informed neural networks (PINNs) in their NN modeling platform. As a physicist (in industry, not academia), much of the data I analyze has underlying physical constraints that are hard to capture within a standard JM...

  • Mass Production of JSL Code Generation via JMP Python Integration Using NVIDIA's Free API (DeepSeek V4 Pro)

    Hey everyone,
    I wanted to share a highly efficient workflow I've developed that bridges JMP's data manipulation capabilities​ with the power of NVIDIA's latest AI models​ running on their free API platform (NIM).
    The core idea is to automate the generation of executable Python/JSL scripts directly within JMP, effectively creating a "content factory" for data analysis tasks.
    The Technical Workflow:
    Dat...

  • PLS2 NIPALS Root Mean Square PRESS

    1.  How to get PRESS values in JMP when using PLS2 NIPALS and Leave out One data ? 2.  When finding RMS PRESS using hand written code I get matching answers for toy problems using (n-1)*k as averaging factor where n is no. of observations and y is number of responses.   3.  But in large problems like Baltic or Gasoline the RMS PRESS was not matching with handwritten code.   But coefficients of the...

  • SPC: Run test 2

    The customised run test2, can be customised from 7 to 11, say you set it to 7 and you have 7 + another 11 points all below the centerline why does the process screen function.  Why does it

    1) Record 11 as the number of alarms, where in fact there is only 1 single stepchange
    2) Surely it shoud just record 1, as there is only 1 stepchange that affect 7+11 points.  You are not goin to ivestigate all 18...
