Designs

[Shru1]

Hey!

I created models using Box-Bhenken, Central composite and Optimal designs. After using the random uniform function to allot random responses within a range, I fitted the models.

Can you evaluate these designs using random responses?If yes, how?

I would also like to know how does JMP calculate the number of experimental trials  for a givenm model?Are there different formulae for calculation of trials? If yes, where can I look up these formulae?Please provide a reference.

Thanks
