• DoE - Continuous factors not allowing to set the decimal format

  Hello, When I try to insert a decimal number in a continuous factor of DoE: it does not allow it. It appears a huge number like the below (instead of 2.2 that I inserted. I tried with "." and "," and the result is always this): How can I solve this? Thank you in advance,Helena G.

• 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 ...
