After using the random uniform function to allot random responses within a range, I fitted the models.</P><P>Can you evaluate these designs using random responses?If yes,&nbsp;how?</P><P>&nbsp;</P><P>I would also like to know how does JMP calculate the number of experimental trials&nbsp; 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.</P><P>&nbsp;</P><P>Thanks</P> Mon, 06 Jun 2016 07:49:39 GMT Shru1 2016-06-06T07:49:39Z https://communities.sas.com/t5/SAS-Data-Science/Designs/m-p/275313#M9608 <P>Hey!</P><P>&nbsp;</P><P>I created models using Box-Bhenken, Central composite and Optimal designs.
