    Hello!We would like to study three different levels of a new process on two products, subject to five preparations. Thus the input variables we have areProcess (A): three levelsProducts (B): two levelsPreparations (C): five levelsA RSM design was made and labels were already printed and sent to be executed. However, the team would like to try a new process (A) without changing the current design.M...

  • "Change Generating Rules" for custom design (is that option just only in screening design?)

    When I'm using Screening Design I can set the generators for the main effects by checking boxes in that menu and then click apply. I can't find how to do this in the Custom Design menu though.  That section isn't there. Is there a reason we can't specify the generating rules for a fractional factorial in custom design? Trying to setup a WP/SP scenario. Otherwise I'd just use the screening design m...

  • Extend a DOE with new discrete numeric values

    Hi, I have performed a DoE on a chemical reaction with four parameters, three with four discrete numeric values and one constant. The DoE gave me some useful insight and I now want to extend the DoE but limit the values of my discrete parameters and change my constant value to a continuous. I've watched many of your YouTube videos and searched the discussions here without luck. I found that my low...

  • How to evaluate Alias structures in D-optimal DOE?

    My understanding is that D-optimal designs can be good for screening experiments, but you'd better hope there aren't any large interaction effects, otherwise they will bias your main effects, or that you should add some suspected 2-way interactions to your optimal design as a way to avoid aliasing effects.  I've been told to avoid Res III fractional factorials, & Plackett-Burman designs for screen...

  • 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...

  • 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...

  • 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?

  • 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 ...
