Hello John,
New issue: the SKEWNESS command fails if the data array has a StdDev = 0 (eg a constant array), because the formula then divides by zero.
The formula in the reference source would also fail - it's not a Stats101 coding error; it's an incomplete algorithm. The formulas on Wikipedia are slightly different...but as far as I can tell they would also divide by zero ;-)
Any Statistics Wizard around with some suggestions?
Gus
