Can we suppose that they used an approximate critical value? I think that, because they say: "In this way, the ?rst column depicts the *actual size of the tests*, while the other columns represent their power.", which could be interpreted as: "using a good estimation of the critical value for JB, we get the actual size of the test with G_0,0.0". Does it make any sense?
