scipy.stats.mstats.trima

scipy.stats.mstats.trima(a, limits=None, inclusive=True, True)

Trims an array by masking the data outside some given limits.

Returns a masked version of the input array.

Parameters

aarray_like

Input array.

limits{None, tuple}, optional

Tuple of (lower limit, upper limit) in absolute values. Values of the input array lower (greater) than the lower (upper) limit will be masked. A limit is None indicates an open interval.

inclusive(bool, bool) tuple, optional

Tuple of (lower flag, upper flag), indicating whether values exactly equal to the lower (upper) limit are allowed.

Examples

>>> from scipy.stats.mstats import trima

>>> a = np.arange(10)

The interval is left-closed and right-open, i.e., [2, 8). Trim the array by keeping only values in the interval.

>>> trima(a, limits=(2, 8), inclusive=(True, False))
masked_array(data=[--, --, 2, 3, 4, 5, 6, 7, --, --],
             mask=[ True,  True, False, False, False, False, False, False,
                    True,  True],
       fill_value=999999)
