{{alias}}( N, K, n )
Returns the standard deviation of a hypergeometric distribution.
If provided `NaN` as any argument, the function returns `NaN`.
If provided a population size `N`, subpopulation size `K` or draws `n` which
is not a nonnegative integer, the function returns `NaN`.
If the number of draws `n` or the subpopulation size `K` exceed population
size `N`, the function returns `NaN`.
Parameters
----------
N: integer
Population size.
K: integer
Subpopulation size.
n: integer
Number of draws.
Returns
-------
out: number
Standard deviation.
