summ x, detail
scalar meanx = r(mean)
scalar medianx = r(p50)
g var1 = abs(x-meanx)
summ var1
scalar d1 = r(mean)
g var2 = abs(x-medianx)
summ var2
scalar d2= r(mean)
di "d1 = " d1 "and  d2 = " d2

dear fellows !

I have a sample with n observations :
are there commands for:
  a)  d1 = 1/n*SUMME(i=1 until n)[|x(i)-x_arithmetic|]
  b)  d2 = 1/n*SUMME(i=1 until n)[|x(i)-median|]
??
|..| means absolut value
x_arithmetic ... arithmetic mean
thank you very much
