For example, the following SAS statements create an output data set named b:

proc reg data=a;
   model y z=x1 x2;
   output out=b
      p=yhat zhat
      r=yresid zresid;
run;

In addition to the variables in the input data set, b contains the following variables:

yhat, with values that are predicted values of the dependent variable y

zhat, with values that are predicted values of the dependent variable z

yresid, with values that are the residual values of y

zresid, with values that are the residual values of z
