I see that there is a difference in the way the “sample skewness” is computed in the CFA books v/s Schweser. In CFA books, the equation is further computed with [n/(n-1) (n-2)]. In Schweser, the equation is further computed with 1/n. Can anyone clarify this one for me please…Thanks!
The Schweser equation is an approximation. If n is sufficiently large, 1/n will be approximately equal to 1/ (n-1)(n-2)
finfan, i don’t think there will be a skewness calculation on the CFA exam. I’d suggest focusing on its meaning.
Check the LOS…I don’t think you have to calc at level I. As maratikus suggests, understand the concept and be able to apply it.
