Returns standard deviation of a specified chi distribution.
Syntax
NTCHISTDEV(
- N
)
Parameters
- N is a parameter of the distribution
(Positive integer).
Remarks
The standard deviation of the distribution is given as:
![\left(N-2\left[\frac{\Gamma\left(\frac{N+1}{2}\right)}{\Gamma\left(\frac{N}{2}\right)}\right]^2\right)^{1/2}](https://s0.wp.com/latex.php?latex=%5Cleft%28N-2%5Cleft%5B%5Cfrac%7B%5CGamma%5Cleft%28%5Cfrac%7BN%2B1%7D%7B2%7D%5Cright%29%7D%7B%5CGamma%5Cleft%28%5Cfrac%7BN%7D%7B2%7D%5Cright%29%7D%5Cright%5D%5E2%5Cright%29%5E%7B1%2F2%7D&bg=T&fg=000000&s=0 "\left(N-2\left[\frac{\Gamma\left(\frac{N+1}{2}\right)}{\Gamma\left(\frac{N}{2}\right)}\right]^2\right)^{1/2}")
