- scipy.stats.moment(a, moment=1, axis=0)¶
Calculates the nth moment about the mean for a sample.
Generally used to calculate coefficients of skewness and kurtosis.
a : array_like
moment : int
order of central moment that is returned
axis : int or None
Axis along which the central moment is computed. If None, then the data array is raveled. The default axis is zero.
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.
