We consider the finite sample power of various tests against serial correlation in the disturbances of a linear … regression when these disturbances follow a stationary long memory process. It emerges that the power depends on the form of the … the disturbances, the power can drop to zero for certain regressors. We also provide a means to detect this zero-power …
