The rationale is that EMD is a completely data-driven technique, which offers the possibility of estimating a trend of arbitrary shape as a sum of low-frequency intrinsic mode functions produced by the EMD. Based on an empirical analysis of EMD, an automatic procedure is proposed to select the requisite intrinsic mode functions. The performance of the EMD trend filtering is evaluated on simulated time series containing different forms of trends. Comparing furthermore to two existing techniques (\u2113<jats:sub>1<\/jats:sub>-trend filtering and Hodrick\u2013Prescott filtering), we observe that the EMD trend filtering performs very similarly, while it does not require assumptions on the form of the trend and it is free from estimation parameters. We also illustrate the performance of the technique on the S&amp;P 500 index, as an example of real-world time series. <\/jats:p>","DOI":"10.1142\/s1793536911000751","type":"journal-article","created":{"date-parts":[[2011,9,8]],"date-time":"2011-09-08T09:53:56Z","timestamp":1315475636000},"page":"41-61","source":"Crossref","is-referenced-by-count":34,"title":["TREND FILTERING: EMPIRICAL MODE DECOMPOSITIONS VERSUS \u2113<sub>1<\/sub> AND HODRICK\u2013PRESCOTT"],"prefix":"10.1142","volume":"03","author":[{"given":"AZADEH","family":"MOGHTADERI","sequence":"first","affiliation":[{"name":"Mathematics and Statistics Department, University Avenue, Jeffery Hall, Queen's University, Kingston, Ontario, Canada, K7L 3N6, Canada"}]},{"given":"PIERRE","family":"BORGNAT","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique, \u00c9cole Normale, Sup\u00e9rieure de Lyon, 46 all\u00e9e d'Italie, Lyon, 69364\/Cedex 07, France"}]},{"given":"PATRICK","family":"FLANDRIN","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique, \u00c9cole Normale, Sup\u00e9rieure de Lyon, 46 all\u00e9e d'Italie, Lyon, 69364\/Cedex 07, France"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2003.821662"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.2307\/2953682"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.1998.0193"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1137\/070690274"},{"key":"rf8","first-page":"14889","volume":"4","author":"Wu Z.","journal-title":"Proc.
