Abstract
We discuss how prior regression on seasonal dummies leads to singulari ties in log-periodogram regression procedures for the detection of lon g memory. We suggest a modified procedure. We illustrate the problems using monthly inflation data from [Hassler and Welters, 1995, Long Mem ory in Inflation Rates: International Evidence, Journal of Business an d Economic Statistics 13, 37-46]. Our new estimates reconfirm their ba sic finding. (C) 1997 Elsevier Science S.A.
