Dear fellows !
I use :
tabstat dosis_corr,stats(mean range sd var sk k iqr)
/dosis_corr is dosis-value in radioactive measurement /
I suppose that sd is appropriate to arithmetic-mean
and var too - accordant sd = sqrt((1/(n-1))*sum[(xi - x_arithm.)^2]),
sum starts at 1 and goes to n/ x_arithmetic .... arithmetic-average .
my question:
how do I get: tabstat dosis_corr,stats(median range sd var sk k iqr)
where sd is a function of median and var too / sd(median) var(median) //
??
thanks
aschbacher andreas
