I am doing Response Surface design analysis in JMP. (yield -> Y. n,p,k -> Macros -> Response Surface Effect). By default, JMP does the analysis by coding the quantitative variables. In BASE SAS I can get the result without coding by using the following code.
In the model specification dialog click on the red triangle pulldown menu next to "Model Specification" and uncheck "Center Polynomials". If any of the independent variables have the coding property then you would also need to go into "column info" for each column of interest and remove the coding property. This latter case would happen if, for example, the table had been generated by the JMP Design of Experiments platform.
Thanks for such quick response. But there is no check box for "Center Polynomials" in Fit Model Window in any of red button pull down menu. There are two red button pull down menu. Attributes & Transform. If you can just give your mail_ID I can send you screenshot of Fit Model window. Or you can send me to firstname.lastname@example.org
I am taking Yield -> Y. Select n, p, k and select Macros -> Response Surface. Click OK. There is no option to uncheck for centring of polynomials.
In the upper left corner of the dialog window there is a red triangle right next to the words "Model Specification". Click on that red triangle to bring up a context menu which includes as its first entry "Center Polynomials". Click it to uncheck it.
