How to get 95% CI output by editing the following code?

[AllSunday]

Hi I am trying to get the output as Mean (95% CI) instead of Mean (SE), but I am struggling with how to edit the code. Please help!

data test;set tt; if domain="zone=1";
Mean_SE = compress(put(round(Estimate, 0.001),8.3)) || " (" || compress(put(round(StdErr, 0.001), 8.3)) || ")";
proc print data=test;
var year Estimate stderr mean_se;

You can just use the below code

Mean = compress(put(round(Estimate, 0.001),8.3)) ;

I think you are making your life difficult by trying to do these calculations inside a text string. Assuming you have a simple T-test here:

lcl=estimate-1.96*stderr;
ucl=estimate+1.96*stderr;

Then you have three variables, ESTIMATE, LCL and UCL that you can print or format any way you want.
