OK. The documentation or examples don't reveal much to what cats should be. For example see: http://docs.pymc-learn.org/en/latest/notebooks/LogisticRegression.html where the data is defined: ``` x_a = np.random.randn(num_samples, num_pred) y_a = np.random.binomial(1,...

From that example it appears that you need to know `cats` before testing. Let me know if I am missing some kind of understanding.
