On the asymptotic standard errors of residual autocorrelations in nonlinear time series modelling
Department of Statistics, University of Hong Kong Hong Kong
The asymptotic distribution of residual autocorrelations for some very general nonlinear time series models is derived. This includes the important class of threshold models. Consequently more accurate standard errors for residual autocorrelations can be obtained facilitating model diagnostic checkings in many situations. A small simulation result applying the methodology to threshold models is reported.
