scipy.stats.mstats.kurtosistest

scipy.stats.mstats.kurtosistest(a, axis=0)

Tests whether a dataset has normal kurtosis

This function tests the null hypothesis that the kurtosis of the population from which the sample was drawn is that of the normal distribution: kurtosis = 3(n-1)/(n+1).

Parameters:

a : array

array of the sample data

axis : int or None

the axis to operate along, or None to work on the whole array. The default is the first axis.

Returns:

z-score : float

The computed z-score for this test.

p-value : float

The 2-sided p-value for the hypothesis test

Notes

Valid only for n>20. The Z-score is set to 0 for bad entries.
