scipy.stats.threshold

scipy.stats.threshold(*args, **kwds)

threshold is deprecated! stats.threshold is deprecated in scipy 0.17.0

Clip array to a given value.

Similar to numpy.clip(), except that values less than threshmin or greater than threshmax are replaced by newval, instead of by threshmin and threshmax respectively.

Parameters:

a : array_like

Data to threshold.

threshmin : float, int or None, optional

Minimum threshold, defaults to None.

threshmax : float, int or None, optional

Maximum threshold, defaults to None.

newval : float or int, optional

Value to put in place of values in a outside of bounds. Defaults to 0.

Returns:

out : ndarray

The clipped input array, with values less than threshmin or greater than threshmax replaced with newval.

Examples

>>> a = np.array([9, 9, 6, 3, 1, 6, 1, 0, 0, 8])
>>> from scipy import stats
>>> stats.threshold(a, threshmin=2, threshmax=8, newval=-1)
array([-1, -1,  6,  3, -1,  6, -1, -1, -1,  8])
