- scipy.stats.mstats.skewtest(a, axis=0)[source]¶
Tests whether the skew is different from the normal distribution.
This function tests the null hypothesis that the skewness of the population that the sample was drawn from is the same as that of a corresponding normal distribution.
Parameters: a : array
The data to be tested
axis : int or None, optional
Axis along which statistics are calculated. Default is 0. If None, compute over the whole array a.
Returns: statistic : float
The computed z-score for this test.
pvalue : float
a 2-sided p-value for the hypothesis test
