statsmodels.stats.stattools.medcouple¶
-
statsmodels.stats.stattools.medcouple(y, axis=0)[source]¶ Calculate the medcouple robust measure of skew.
- Parameters
- yarray_like
Data to compute use in the estimator.
- axis{
int,None} Axis along which the medcouple statistic is computed. If None, the entire array is used.
- Returns
- mc
ndarray The medcouple statistic with the same shape as y, with the specified axis removed.
- mc
Notes
The current algorithm requires a O(N**2) memory allocations, and so may not work for very large arrays (N>10000).
