how to automatically get the smaple size n and compute 1/n *X

desireatem — Thu, 11 Jul 2013 22:57:01 GMT

Hi I have this data set

I what t0 compute T=1/n * S,

For this it looks easy because n=5 (since there are five observations). But I have many data with varying ‘n’, so I want SAS to count and get the n for each data then compute T=1/n *S;

There are lots of way to get it. Here is one way.

%let dsid=%sysfunc(open(sashelp.class));

%let nobs=%sysfunc(attrn(&dsid,nlobs));

%let dsid=%sysfunc(close(&dsid));

%put &nobs ;
