proc reg data=p7_15;
model y=x1 x2/p cli;  /*p means point forecast and cli means the confidence intervals estimation 95% */
output out=abc p=yhat stdi=sef lcl=lcl ucl=ucl; /* create a new data set called abc, yhat is the predicted point value, sef is the error terms of the forecast, lcl is the upper limit and ucl is the lower limit */
run;
