Least absolute deviations estimation for ARCH and GARCH models

Abstract

Hall & Yao (2003) showed that, for ARCH/GARCH, i.e. autoregressive conditional heteroscedastic/generalised autoregressive conditional heteroscedastic, models with heavy-tailed errors, the conventional maximum quasilikelihood estimator suffers from complex limit distributions and slow convergence rates. In this paper three types of absolute deviations estimator have been examined, and the one based on logarithmic transformation turns out to be particularly appealing. We have shown that this estimator is asymptotically normal and unbiased. Furthermore it enjoys the standard convergence rate of n-super-1/2 regardless of whether the errors are heavy-tailed or not. Simulation lends further support to our theoretical results. Copyright Biometrika Trust 2003, Oxford University Press.
