I often have to report different summary measures of different vars by
group-level in one table. For example I'd like to display the proportion
overweight pre-school children (mean of dummy-var var1), the number of
(sum of counting-var var2) and the median score of a test (p50 of var3)

    city     | overweight  cases  score  
  Frankfurt  |   0.12        77    53   
  Wiesbaden  |   0.11       112    68    

tabstat (one-by-one or with all vars and summary measures specified
simultaniously) give the results but one needs a lot of copy & paste to
spreadsheet to get it in shape. collapse is of course another solution
slow with big datasets and certainly a very big transformation just to
obtain some descriptive statistics.

If there's a solution already available I would be glad to know. I'm
thinking of a command where (as in collapse) summary measures can
individually be assigned to vars, like:  tabstat2 (mean) var1 (sum) var2
(p50) var3, by(group). 


Fred Wolfe pointed to the unofficial -fsum- command which may or may
not fulfill Stefan's needs.

I think the official -table- command does the job:

    . sysuse auto
    . table foreign, contents(freq mean mpg sum price p50 length)
     Car type |       Freq.    mean(mpg)   sum(price)  med(length)
     Domestic |          52      19.8269       315766          200
      Foreign |          22      24.7727       140463          170

Hope this helps
