Consistency and asymptotic normality are proven for stationary, nonstationary, and noninvertible series, permitting straightforward standard inference of interesting hypotheses such as the existence of unit roots and equality of memory parameters at some or all seasonal frequencies, which can be used as a prior test for the application of seasonal differencing filters. The effects of unknown deterministic terms are also discussed. Finally, the finite sample performance is analyzed in an extensive Monte Carlo exercise and an application to an U.S. Industrial Production index.\n                  <\/jats:p>","DOI":"10.1017\/s0266466619000422","type":"journal-article","created":{"date-parts":[[2020,3,5]],"date-time":"2020-03-05T01:43:49Z","timestamp":1583372629000},"page":"1064-1098","source":"Crossref","is-referenced-by-count":9,"title":["EXACT LOCAL WHITTLE ESTIMATION IN LONG MEMORY TIME SERIES WITH MULTIPLE POLES"],"prefix":"10.1017","volume":"36","author":[{"given":"Josu","family":"Arteche","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2020,3,5]]},"reference":[{"key":"S0266466619000422_r23","doi-asserted-by":"publisher","DOI":"10.1111\/1467-9892.00179"},{"key":"S0266466619000422_r27","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1990.10476206"},{"key":"S0266466619000422_r30","doi-asserted-by":"publisher","DOI":"10.1214\/aos\/1176324317"},{"key":"S0266466619000422_r9","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1080\/07350015.1995.10524598","article-title":"Are seasonal patterns constant over time?
