scipy.stats.trimboth

scipy.stats.trimboth(a, proportiontocut, axis=0)

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

aarray_like

Data to trim.

proportiontocutfloat

Proportion (in range 0-1) of total data set to trim of each end.

axisint or None, optional

Axis along which to trim data. Default is 0. If None, compute over the whole array a.

Returns

outndarray

Trimmed version of array a. The order of the trimmed content is undefined.
