摘要
The Imhof procedure is used to calculate the exact finite-sample distributions of alternative heteroskedasticity robust Wald-type tests of scalar linear hypothesis in the normal linear model. The tests are distinguished by the variance estimator that they use. These include the White-Eicker and jackknife estimators. The calculations demonstrate the importance of regression design in determining the quality of conventional first-order asymptotic approximations to the null distributions of the tests. © 1991.
