st: accessing sum of weights

["Feiveson, Alan H. (JSC-SK311)" <alan.h.feiveson@nasa.gov>]

Hello - After running a weighted regression, say with -regress-, I can't
seem to find where the sum of the weights is stored for further access.
For example, it is not listed in -erturn list- Is this sum directly
available, or is there no recourse other than re-calculating it with a
separate -sum- command? 

Thanks
