Re: Skewness

Mr. David Heiser


In a more “in dept” consult I found that SKEWNESS is evaluated by different formulas.(MATHWORLD).
If you agree and have time to spend we can made a short “tour” in this particular (same research) in order to find the CONFIDENCE INTERVALS of skewness (K. Pearson)
GAMA1=MIU3 / MIU2^1.5
As I am not an expert in this particular I would be very pleased if you post what are the currently used estimators of the CENTRAL MOMENTS (I think that part of the difficulty is here).
As you notice I am able to simulate (Monte Carlo) all this “stuff”. I will not spend too much time, 1-2 month, I think.
It would be “great” if you could check my results on a “grown” (faster) computer, or even on a PC. Have you access to one?
If I could check the literature results I do it, is my “philosophy”. I detest to be a Museum curator (a keeper of the Holy Texts). I do not think that to confirm myself is a lost of time.
It would be said that your comment “The formula is way off”
summarised a “nol me tangere” attitude.


I expect to hear you soon.
