Before Change

        Confirm Gelman-Rubin statistic is far from 1 for a small number of samples.
        trace = self.fake_trace(6)

        n_samples = 1000

After Change

            np.random.randn(100, 1)]))
        assert 1 / self.good_rhat > rhat or self.good_rhat < rhat

    def test_effective_n_array(self):
        eff_n = effective_n(np.random.randn(4, 100))
        assert eff_n > 100
