estimating the memory parameter can avoid bias incurred by misspecification of the short memory component. We introduce a broad … to a smooth interpolation of asymptotic variances. The bias of these two estimates also differs to higher order, and we … also show how bias, and asymptotic mean square error, can be reduced, across the class of estimates studied, by means of a …
