Web• It is straightforward to create one-sided Wald and score tests (i.e., tests of H 0: θ = θ 0 against H 1: θ > θ 0 or H 1: θ < θ 0), but this is more difficult with a likelihood ratio test. • The score test does not require ˆθ n whereas the other two tests do. • The Wald test is most easily interpretable and yields immediate ...
