A power approximation for the Kenward and Roger Wald test in the linear mixed model

We derive a noncentral [Image: see text] power approximation for the Kenward and Roger test. We use a method of moments approach to form an approximate distribution for the Kenward and Roger scaled Wald statistic, under the alternative. The result depends on the approximate moments of the unscaled W...
