It is well known that, under some conditions, tests are asymptotically equivalent, and are optimal in the sense that the local power of these tests are equal to the maximum that can be achieved. However, in most practical situations, the density function f is unknown.

An issue that arises in applications involving the ARCH-in-Mean (ARCH-M) model is whether or not the error variance is constant over time. A proper statistical formulation of this as a test of hypothesis presents two difficulties. First, the model does not satisfy the standard regularity...
