• Custom DoE screening design

  I have two very basic questions about custom DoE screening design.1. If I only wanted to know which main effects are significant to my responses and use the custom main effect screening design with the default run numbers given by JMP, how can I be sure whether it is the main effect or other confounding two-way interaction that is really significant? If the model analysis shows factor A is signifi...

• Guidelines for fitting custom screening DoE

  Hello JMP User Community, I am seeking for some suggestions/guidelines to fit a Custom Screening DoE for main effects. Below is the screen shot of the model fitting. My thought process is to remove those factors with t ratio less than 2 one by one until all factors left with t ratio above 2 and then use those factors to conduct a Response Surface Design for more detailed investigation. I will also...

• DOE - replicates vs. repetitions

  I need to to design an experiment to determine temperature - Temp influence on pH.Let's assume, temperature is a continuous variable in range [20,23].And pH is continuous as well, good within range [5,7], but perfect in the center.On a daily basis, in normal conditions we measure every sample 3 times (pseudoreplicates).Is 3 in this case number of replicates I should use in JMP? Or it's only repeti...

• How to assign a series of value to selected rows without using a for loop？

  Hi, all
  I used get rows where() to get a series of rows and want to assign the values in the rows under column b to the same rows under another column, like below   rows = dt << get rows where (column("b")[ ] == "xxx");
column ("a")[rows] = column ("b") [rows];
  But it doesn't work, want to know is there any way to assign a series of values to selected rows without using a for loop？
  Thank you

• How are confidence limits for Fit Curve Equivalence Test generated?

  I've been using the Fit Curve platform to model a pair of curves and then compare them using the Equivalence Test, Test Parallelism, and ANOM options. However, I've also had to fit one of my pairs with a custom nonlinear model using the Nonlinear platform, which doesn't have any of these three options - as a result, I've been trying to essentially manually generate an equivalence test or ANOM. For...
