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). The trimmed values are the lowest and highest ones. Slices off less if proportion results in a non-integer slice index (i.e., conservatively slices off`proportiontocut`).
Parameters: a : array_like
Data to trim.
proportiontocut : float
Proportion (in range 0-1) of total data set to trim of each end.
axis : int or None, optional
Axis along which to trim data. Default is 0. If None, compute over the whole array a.
Returns: out : ndarray
Trimmed version of array a. The order of the trimmed content is undefined.
