An array containing the values for which

axis: int or None, optional. :

if equal None, ravel array first. If equal to an integer, this will be the axis over which to operate. Defaults to 0.

ddof: int :

Delta degrees-of-freedom. How many degrees of freedom to adjust for bias in limited samples relative to the population estimate of variance
