statsmodels.sandbox.distributions.extras.NormExpan_gen.entropy

NormExpan_gen.entropy(*args, **kwds)

Differential entropy of the RV.

Parameters:

• arg2, arg3,.. (arg1,) – 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
