Description:
 def loglike(self, y, f):
 r""" Bernoulli log likelihood. Parameters y: ndarray array of 0, 1 valued integers of targets f: ndarray latent function from the GLM prior (:math:`\mathbf{f} = \boldsymbol\Phi \mathbf{w}`) Returns ------- logp: ndarray the log likelihood of each y given each f under this likelihood. """

        ll = y * f - softplus(f)
