proc fastclus data=sashelp.iris  outstat=want distance
maxclusters=3 maxiter=100;
var _numeric_;

Each of the variables in effect is a separate dimension. The overal centroid would be the point with coordinates corresponding to the centroid of each dimension.

Honestly ,I don't know what is your mean .

Change it into one cluster ?

maxclusters=1

In your output{snapshot provided by you in ur answer} , visible that center value for over_all is missing. I am looking for that value. what would be that value if i want to know that.

Thanks in advance.

But That doesn't make any sense, Maybe you could PROC TRANSPOSE it .

Or are you looking for proc varclus ?
