• Space Filling DOE, with Fast Flexible Filling, using table Constraint of factor2(factor1,factor3) to limit DOE space.

  Hi there. I'm having a knightmare setting constraints in JMP for a Space Filling DOE. I want to explore the DOE space fully, but without driving test samples to failure. So, I have generated a table to set maximum limits of one of the factors as a function of another 2 factors. I don't seem to be able to use the table directly, so am trying Use Disallowed Combinations Script. Trying a bicubic equa...

• Error when comparing multiple DOE designs

  Hello,
  
  Can someone clarify why I get this error message when comparing the 4 custom DOE designs (2 designs have 18 runs, the other has 36 runs -includes duplicates- and the last has 54 runs-includes triplicates), and what this message means?
  "Model for primary design cannot be fit by all designs. Removing inestimable model terms."
  
  Thank you!!

• How do I know if my DOE Custom Design is balanced?

  Hi!
  
  I am using Custom Design to generate a DOE design. I was wondering how can I make sure that my design is balanced? The course I took on Custom Design of Experiments mentioned that this type of design is by default balanced, but I want to make sure I didn't mess anything up in my design and it is balanced. I didn't quite understand the "how to know if its balanced" part. Does design balance have...

• Why is graph builder displaying an ordinal axis as interval?

  More a quibble than anything else, but I have some ordinal numeric data and the axis is being set up as interval.  So I have data for 14, 14.6, 50, but nothing between.  I expect them to be in order, but without an interpretation of the interval spacing.  Basically the definition of ordinal.  Yet the axis is presenting the ordinal data as existing on a continuous interval, so all the steps between...

• Adding a complex constrain to a Custom Design with 4 factors

  Hello,
  
  I am creating a Custom Design with 4 factors (Factors A, B, C & D).
  
  I have a question about a constraint that has to do with factors B and D.
  - Factor B is actually the number of reactions done in sequence in the same experiment. This can be 1 reaction, 2, 3 or more reactions in sequence. I set the range as 1-3 (not higher because I am not interested at the moment in >3 reactions in sequence).
