You might say that you are performing a Chow test, but I say that you are performing a Wald test.

For d< 0, both tests converge to zero under … how to mask shape in photoshop

WebMay 22, 2024 · We also show that the sup Wald test for breaks in the unconditional mean and variance does not have the same size distortions, yet benefits from similar power to its conditional counterpart in correctly specified models. Hence, we propose using it as an alternative and complementary test for breaks.
