Long and short memory conditional heteroscedasticity in estimating the memory parameter of levels

Robinson, Peter M.; Henry, Marc - London School of Economics (LSE) - 1998

Semiparametric estimates of long memory seem useful in the analysis of long financial time series because they are consistent under much broader conditions than parametric estimates. However, recent large sample theory for semiparametric estimates forbids conditional heteroscedasticity. We show...
