Compared with other methods, our method can capture some characteristics that are pertinent to the time series and is much easier to implement. An order selection method is introduced and developed. Some real data sets are analysed.<\/jats:p>","DOI":"10.1111\/1467-9868.00238","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T19:36:21Z","timestamp":1047497781000},"page":"383-397","source":"Crossref","is-referenced-by-count":1,"title":["On the Estimation of an Instantaneous Transformation for Time Series"],"prefix":"10.1093","volume":"62","author":[{"given":"Yingcun","family":"Xia","sequence":"first","affiliation":[{"name":"University of Hong Kong , People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Howell","family":"Tong","sequence":"additional","affiliation":[{"name":"University of Hong Kong , People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.
