scipy.stats.mstats.moment

scipy.stats.mstats.moment(a, moment=1, axis=0)

Calculates the nth moment about the mean for a sample.

Parameters:

aarray_like

data

momentint, optional

order of central moment that is returned

axisint 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 momentndarray 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.
