We use GARCH and regime switching models to compare the reliability<br />
of recently proposed misspecication tests. Our simulations indicate that<br />
simple moment based LM type tests are more reliable than other moment<br />
based tests or tests that employ the empirical distribution function or non-<br />
parametric methods.</p>
