scipy.stats.tmax#
- scipy.stats.tmax(a, upperlimit=None, axis=0, inclusive=True, nan_policy='propagate', *, keepdims=False)[source]#
Compute the trimmed maximum.
This function computes the maximum value of an array along a given axis, while ignoring values larger than a specified upper limit.
- Parameters:
- aarray_like
Array of values.
- upperlimitNone or float, optional
Values in the input array greater than the given limit will be ignored. When upperlimit is None, then all values are used. The default value is None.
- axisint or None, default: 0
If an int, the axis of the input along which to compute the statistic. The statistic of each axis-slice (e.g. row) of the input will appear in a corresponding element of the output. If
None
, the input will be raveled before computing the statistic.- inclusive{True, False}, optional
This flag determines whether values exactly equal to the upper limit are included. The default value is True.
- nan_policy{‘propagate’, ‘omit’, ‘raise’}
Defines how to handle input NaNs.
propagate
: if a NaN is present in the axis slice (e.g. row) along which the statistic is computed, the corresponding entry of the output will be NaN.omit
: NaNs will be omitted when performing the calculation. If insufficient data remains in the axis slice along which the statistic is computed, the corresponding entry of the output will be NaN.raise
: if a NaN is present, aValueError
will be raised.
- keepdimsbool, default: False
If this is set to True, the axes which are reduced are left in the result as dimensions with size one. With this option, the result will broadcast correctly against the input array.
- Returns:
- tmaxfloat, int or ndarray
Trimmed maximum.
Notes
Beginning in SciPy 1.9,
np.matrix
inputs (not recommended for new code) are converted tonp.ndarray
before the calculation is performed. In this case, the output will be a scalar ornp.ndarray
of appropriate shape rather than a 2Dnp.matrix
. Similarly, while masked elements of masked arrays are ignored, the output will be a scalar ornp.ndarray
rather than a masked array withmask=False
.Examples
>>> import numpy as np >>> from scipy import stats >>> x = np.arange(20) >>> stats.tmax(x) 19
>>> stats.tmax(x, 13) 13
>>> stats.tmax(x, 13, inclusive=False) 12
