I need x to = 1 - 178 (observations). So far my commands are:
/* transform consumption and income variables into logs*/
data session3.combinedfiles;
set session3.combinedfiles;
y=log(PCECC96);
x1=log(DPIC96);
x2=log(MPRIME);
run;
/* multiple regression model: suppose Y now depends on x1 and x2: Y = beta0+ beta1 x1 + beta2 x2 + error*/
proc reg data=session3.combinedfiles;
model y = x1 x2;
output out=session3.est_data1 residual=e predicted=y_hat lcl=lower95 ucl=upper95;
run;
quit;
As you can see I don't have a column called X which simply equals id. Thank you for the help.
Simply add a statement:
/* transform consumption and income variables into logs*/
data session3.combinedfiles;
set session3.combinedfiles;
y=log(PCECC96);
x1=log(DPIC96);
x2=log(MPRIME);
ID=_n_;
run;
I still don't have a column that says X and under it the numbers from 1 through 178.
Something went wrong. Check the log. You should have a new column called ID in your OUT= dataset.
If you want the variable to be named x, then use
x = _n_;
