• Which one to define effect size: Logworth or Scaled Estimates ?

  Hi Community, I have a question concerning which criteria is more appropriate to determine the importance of the impact of a factor: is it the "logworth" (clearer visualization of p values) or is it the "scaled estimates" ? When working with one of the sample datas (Donev Mixture Data),  I got these results for Logworth and for scaled estimates (images below): Logworth: Scaled Estimates: You can s...

• Statistical interpretation of a split-plot DOE design

  Hi, I am not used to statistical interpretation of split-plot DoE and I don't know what is the impact if I have a "wald p value" < 5%.I know that if it is higher than 5%, whole plot and subplot have no impact on the plan so if its value is < 5% it meas that whole plot and sub plot have an impact on the plan, but how can I analyze that? Thank you for your help.

• DOE Costom Design with standard factors or with Mixture Factors?

  I am facing the following problem:I have a bunch of factors that are ingredients of a solution:Ingredient A (2 - 20%)Ingredient B (0 - 4%)Ingredient C (5 - 20%)whereas behind Ingredient B and C a selection of categorial Ingredients exists.Further, I have several process factors:Pressure 200 - 400Runs 2 - 4 Responses:StabilityCosts Aim of that DOE is to find out which is the best formulation with c...

• What does the term X1*X1 mean in an RSM design?

  Hello, When I'm using DOE and I click 2nd order interactions, the model will add combinations of every interaction of my factors, e.g. X1*X2, X2*X3 and X1*X3. This makes sense to me because these terms tell me about the combined effect of two factors on my response. However, if I click the RSM button it will add quadratic terms such as X1*X1, X2*X2 and X3*X3. My question is, what physical meaning ...

• Screening Design and Response Surface Design with Multiple Responses

  Hi,  I use JMP Pro 17 for response surface design. I have 13 design variables. First I perform a Screening Design to decide on which 8 parameters are the most effective on the response, then I vary those 8 parameters to conduct a Response Surface Design. (8 is the maximum number of variables JMP accepts for Response Surface Design.) I conduct 33 experiments (with 1 center point) for Screening Desi...
