def moment(a, moment=1, axis=0) 

Description

moment.__doc__

    Calculates the nth moment about the mean for a sample.

    Parameters
    ----------
    a : array_like
       data
    moment : int, optional
       order of central moment that is returned
    axis : int or None, optional
       Axis along which the central moment is computed. Default is 0.
       If None, compute over the whole array `a`.

    Returns
    -------
    n-th central moment : ndarray or float
       The appropriate moment along the given axis or over all values if axis
       is None. The denominator for the moment calculation is the number of
       observations, no degrees of freedom correction is done.
