Simulation-based finite-sample tests for heteroskedasticity and ARCH effects
2004, Journal of EconometricsCitation Excerpt :In addition, most of the references cited above include Monte Carlo evidence on the relative performance of various tests. The main findings that emerge from these studies are the following: (i) no single test has the greatest power against all alternatives; (ii) tests based on OLS residuals perform best; (iii) the actual level of asymptotically justified tests is often quite far from the nominal level: some are over-sized (see, for example, Honda, 1988; Ali and Giaccotto, 1984; Binkley, 1992), while others are heavily under-sized, leading to important power losses (see Lee and King, 1993; Evans, 1992; Honda, 1988, Griffiths and Surekha, 1986; Binkley, 1992); (iv) the incidence of inconclusiveness is high among the bounds tests; (v) the exact tests compare favorably with asymptotic tests but can be quite difficult to implement in practice. Of course, these conclusions may be influenced by the special assumptions and simulation designs that were considered.
