<br/><br/> There are some techniques for obtaning the exact moments of econometric estimators and test Statistics . These techniques require the specification of the density of the data vector Y  for example normal and they provid the results which hold for any size of the data . The exact results are however, diffcult to derive under a general non - normal framework
