• Margin of error of predictor screening

  Hi!I was wondering if I can get the margin of error of a predictor screening model I run to be able to compare the portion of the predictors across different groups within one sample -by running the model "By" the different groups- and understand if the differences are true differences or not -similarly to the concept of statistically significant differences in research/ survey data-.Does this mak...

• Order of addition experiments, simultaneous addition, and delayed addition

  Hello - I am working on an process that has an obvious order of addition effect. I have a plugin from JMP that uses a pairwise ordering scheme that can be plugged in as a covariate factor. But, one of the components is a powder, so there is the choice to predissolve it in the solvent being used, or to add it directly as a powder. Also, there could be some benefit to having some components simultan...

• No retrospective Parameter Power calculation available in Split-Plot analysis?

  In the analysis of a typical DOE (using Standard Least Squares), there is a possibility to view the retrospective Parameter Power(Estimates > Parameter Power).However, when analysing a Split-Plot DOE (using REML), this option is not available.I can imagine it is more complex to calculate, but would have expected it to be available somehow.

• How to know whether my choice design is orthogonal? (Validity of choice experime

  For my master thesis I made a Discrete Choice Experminent in JMP. The following design roled out of JMP (with 4 attributes, 3 levels each, and 16 choice sets)  When I checked the validity of the design I made a correlation matrix of dummy variables. The attributes Gar2/Gar3 (warranty) and EEO 450,525 and 600 (efficiency of energy conversion) correlates with each other. Is this correlation to high ...

• DoE with replicates on the extremities

  Hello, I would appreciate support on the following topic:- I pretend to perform a Full Factorial DoE with 2 center points and replicates on the extremities. When I set up my design I chose 1 replicate (in the tab below) and then the DoE appears one replicate for each experience. Is it possible to set up just one replicate for each one of the extreme conditions? How? Thank you in advance,Helena
