WebNotes ----- The integration behavior of this function is inherited from `scipy.integrate.quad`. Neither this function nor `scipy.integrate.quad` can verify whether the integral exists or is finite. For example ``cauchy(0).mean()`` returns ``np.nan`` and ``cauchy(0).expect()`` returns ``0.0``. The function is not vectorized.
