Dear fellows !

I use :
tabstat dosis_corr,stats(mean range sd var sk k iqr)
I suppose that sd is correspondet to arithmetic-mean
and var too - accordant sd = sqrt((1/(n-1))*sum[(xi - x_rithm.)^2])
sum starts at 1 and goes to n/ x_arithmetic .... arithmetic-average
my question:
how do I get:  tabstat dosis_corr,stats(mean range sd var sk k iqr)
where sd is a unction of mean and var too ??
thanks 
aschbacher andreas
