scipy.stats.rv_continuous.entropy

rv_continuous.entropy(*args, **kwds)[source]

Differential entropy of the RV.

Parameters:

arg1, arg2, arg3,... : array_like

The shape parameter(s) for the distribution (see docstring of the instance object for more information).

loc : array_like, optional

Location parameter (default=0).

scale : array_like, optional (continuous distributions only).

Scale parameter (default=1).

Notes

Entropy is defined base e:

>>>
>>> drv = rv_discrete(values=((0, 1), (0.5, 0.5)))
>>> np.allclose(drv.entropy(), np.log(2.0))
True
