Hi everyone,
I made a quadratic regression thanks to the REG procedure. As I want to test a quadratic model without intercept, I specified the "noint" option.
Ex : proc reg data=tab; model Y = X X*X / noint; run; quit;
Now, I want to test the lack of fit of my regression. So, I know that I can do that with the RSREG procedure.
Ex : proc rsreg data=tab; model Y= X X*X / covar=1 lackfit; run; quit;
But, it computes the LOF with the intercept and I don't the intercept in the model.
I check in the SAS help but I've found no option to suppress the intercept. Does someone know how to do this ?
By advance, thanks a lot
Céline
