will be supportive anyway, as always. 
I would like to measure the amount of variability I have for one specific measure in 2 different groups 
of patients. of course I could use the standard deviation for that but I would like also to 
create an index of that variability and be able to compare that index between the 2 groups with a formal stat test.
Note that in this case I am not interested in central tendency measures (mean or median) but just in a way to quantitate 
the variability, present that as an index and compare among 2 (or more) groups. 
How would you proceed in STATA ? <<
