• Mixture design - specifying linear constraints

  I wanted to have mixture design or custom design with 5 raw materials (P1, P2, X, Y, Z). And in this design, sum of  two of the same type of  raw materials P1 & P2 should be between 0.2 and 0.4. I tried to use linear constraints. But JMP is saying that the constraints are wrong. What will be the right constraint for that? and is this possible to do? And is it possible to include the combined effec...

• Guidance on mixtures design approach for a 6 component mixture with only 3 variables.

  Hello all, I'm looking to set up a mixtures design for a mixture which overall contains 6 components at these percentages below, but I only want to use three of these as my input variables. Components 4 to 6 must add up to 15 %. Component 1: 70 %Component 2: 10 %Component 3: 5 %Component 4: 0 - 5%Component 5: 0 - 5 %Component 6: 0 - 5 % When setting up the DoE, how do I remove Components 1, 2 and ...

• removing terms from a model following a designed experment

  Ok, suppose I've conducted a full factorial design with four 2-level factors. When fitting the model I've included all 2-way interactions. Some of the factors' main effects and interactions are not significant at 0.05. If I then remove the least significant factors (those at the bottom of the effect summary table), some of the non-significant terms become significant. If I were trying to develop t...

• how to get fixed effect tests table to appear

  I have a continuous response variable (Average) and a categorical predictor (Treatment) with labels 1 through 14 indicating the 14 levels. I have set the Treatment variable as ordinal, and was able to use the fit model function to obtain the least squares means table and least square means plot. However, I am unable to figure out how to obtain a table for a type 3 test of fixed effects. Specifical...

• how to get a type 3 fixed effects test table

  Does anybody know how to get a type 3 fixed effects test in JMP using the Fit Model option? I have a continuous response variable and a categorical predictor. I need a table that lists the denominator degrees of freedom for the F value. It should be a table that comes with the name Fixed Effect Tests. Please help!
