再次请教

data result(drop=sum);
set result;
retain sum mean;
if _n_=1 then sum=0;
sum+log(volume);
if _n_=61 then mean=sum/61;
if _n_>61 then do;
abVolume=log(volume)-mean;
output;
end;
run;
用这段代码算出abvolume 后想看看abvolume 数据是不是significant的比如说要做t-test， 应该再怎么写呢，谢谢啦

I am not so sure how you want to do the test, but for one-sample t-test, here is the way to do it.

proc ttest data=result;
var abvolume;
run;
