def predict_logit(self, x, **kwargs):
        '''Compute the logit values that underlie the softmax output.

        Parameters
        ----------
        x : ndarray (num-examples, num-variables)
            An array containing examples to classify. Examples are given as the

        Returns
        -------
        l : ndarray (num-examples, num-classes)
            An array of posterior class logit values, one row of logit values
            per row of input data.
