scipy.stats.mstats.trimboth

scipy.stats.mstats.trimboth(data, proportiontocut=0.2, inclusive=(True, True), axis=None)[source]

Trims the smallest and largest data values.

Trims the data by masking the int(proportiontocut * n) smallest and int(proportiontocut * n) largest values of data along the given axis, where n is the number of unmasked values before trimming.

Parameters
datandarray

Data to trim.

proportiontocutfloat, optional

Percentage of trimming (as a float between 0 and 1). If n is the number of unmasked values before trimming, the number of values after trimming is (1 - 2*proportiontocut) * n. Default is 0.2.

inclusive{(bool, bool) tuple}, optional

Tuple indicating whether the number of data being masked on each side should be rounded (True) or truncated (False).

axisint, optional

Axis along which to perform the trimming. If None, the input array is first flattened.
