I have six factors. First four are discrete X1, X2, X3 and X4 ( three are 2 level and one is 3 level). I would like to use only one factor a time from first four ( either one from X1, X2, X3 and X4) with remaining two factors. 

for example, I want to use only one kind of sugar at a time.

X1: Regular sugar, 1 or 2 grams

X2: Brown sugar, 1 or 2 grams

X3: Honey, 1 or 2 grams

X4: Sweetener, 1, 1.5 or 2 grams

Thanks

I recommend using DOE > Custom Design for this purpose. It produces an optimal design based on your specifications.

 

1. Select DOE > Custom Design
2. Double-click Y and enter the name of your response.
3. Change the Goal to match the purpose of your response.
4. Click Add Factor and select Categorical > 4 Levels.
5. Type Sweetener for the name, then press Tab to enter the four choices for sweetener.
6. Click Add Factor and select Continuous.
7. Type Amount and enter 1 for Low and 2 for High.
8. Click Continue.
9. Click Interactions and select 2nd if you think that the effect of changing the Amount is not the same for all choices of the sweetener.
   
   
   
   
10. Enter the number of runs that you want. The minimum number is equal to the number of parameters in the model. I recommend running more than the minimum. I will use 16 but the actual number depends on several aspects of your situation.
11. Click Make Design.
    
    
    
    
12. Click Make Table when the design is ready.

 

Please see Help > JMP Documentation Library > Design of Experiments guide for more information and examples.

 

Why do your want runs with Amount = 1.5?
