NTCHISKEW

Returns skewness of a specified chi distribution.

Syntax

NTCHISKEW(

  • N

)

 

Parameters

  • N is a parameter of the distribution N (Positive integer).

Remarks

The skewness of the distribution is given as:

\frac{\mu(3)-3\mu(2)\mu(1)+2\mu^3(1)}{\sigma^3}
\mu(r)=\frac{2^{\frac{r}{2}}\Gamma\left(\frac{N+r}{2}\right)}{\Gamma\left(\frac{N}{2}\right)}

, where \sigma is standard deviation and \Gamma(\cdot) is gamma function.
