Proc Reg Output 'parameterestimates' was not created

[Jie111]

I used proc reg and want to output parameterestimates. 

The first time, it works well and output the table I want.

74                            ods output ParameterEstimates=pest2;
75                             ods listing close;
76                              proc reg data=rush.slope_cha_merge_mri;
77                                    model total_GMV_n =bmi_slope apoe_e4/clb;
78                             run;

NOTE: The data set WORK.PEST2 has 3 observations and 10 variables.

However,  when I rerun the code, there is a warning and parameterestimates could not be output. And the warning is still here even I changed the name of output table.

Does anyone know how to resolve this?

End interactive procedures with a QUIT statement, and always put ODS OUTPUT statements after the PROC statement (even though it is not always required).

Proc REG want a Quit ; statement to end the procedure. It is one of the procedures that is interactive, meaning that you can issue part of the Proc Reg code. Then run additional Model statements with the same data. Until you execute a QUIT; the procedure should show that it is still running.

"Run group" processing means that you can submit the following code:

proc reg data=rush.slope_cha_merge_mri;
   model total_GMV_n =bmi_slope apoe_e4/clb;
run;

look at the output. Then perhaps run this:

   model total_GMV_n =bmi_slope /clb;
run;

the second run means to execute the new model.

Then you submit a QUIT; to end the procedure.

There are a number of procedures that support this sort of behavior. In this case it means that you don't have to keep executing the options on the Proc statement that would require reloading the data for each model.
