statsmodels.stats.robust_compare.trimboth¶
- statsmodels.stats.robust_compare.trimboth(a, proportiontocut, axis=0)[source]¶
Slices off a proportion of items from both ends of an array.
Slices off the passed proportion of items from both ends of the passed array (i.e., with proportiontocut = 0.1, slices leftmost 10% and rightmost 10% of scores). You must pre-sort the array if you want ‘proper’ trimming. Slices off less if proportion results in a non-integer slice index (i.e., conservatively slices off proportiontocut).
- Parameters:
- Returns:
- out
ndarray
Trimmed version of array a.
- out
Examples
>>> from scipy import stats >>> a = np.arange(20) >>> b = stats.trimboth(a, 0.1) >>> b.shape (16,)
