Robinson, P. (1995), "Gaussian Semiparametric Estimation of Long Range Dependence", Annals of Statistics, 23(5), p. 1630--1661. While we're on the subject, the modified version by Shimotsu and Phillips would probably be nice to have too: Shimotsu, K. and Phillips, PCB (2005) "Exact local Whittle estimation of fractional integration", Annals of Statistics, 33(4), p. 1890--1933 Riccardo (Jack) Lucchetti Dipartimento di Economia Università Politecnica delle Marche r.lucchetti(a)univpm.it http://www.econ.univpm.it/lucchetti
