Generally speaking, the functional relationship of the profile data rarely occurs in linear form, and the real data usually do not follow normal distribution. Thus, in this paper, the functional relationship of profile data is described via a nonparametric regression model and a nonparametric exponentially weighted moving average (EWMA) control chart is developed for detecting the process shifts for nonlinear profile data in the Phase II monitoring.<\/jats:p><jats:p>We first fit the nonlinear profile data via a support vector regression model and use the fitted values to calculate the five metrics. Then, the nonparametric EWMA control chart with the five metrics can be constructed accordingly. Moreover, a simulation study is conducted to evaluate the detecting performance of the new control chart under various process shifts using the out\u2010of\u2010control average run length. Finally, a realistic nonlinear profile example is used to demonstrate the usefulness of our proposed nonparametric EWMA control chart and its monitoring schemes. It is expected that the proposed nonparametric EWMA control chart can enhance the monitoring efficiency for nonlinear profile data in the phase II study.<\/jats:p>","DOI":"10.1002\/qre.2385","type":"journal-article","created":{"date-parts":[[2018,9,21]],"date-time":"2018-09-21T23:36:50Z","timestamp":1537573010000},"page":"127-135","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Monitoring nonlinear profile data using support vector regression method"],"prefix":"10.1002","volume":"35","author":[{"given":"Chung\u2010I","family":"Li","sequence":"first","affiliation":[{"name":"Department of Statistics National Cheng Kung University  Tainan Taiwan, ROC"}]},{"given":"Jeh\u2010Nan","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Statistics National Cheng Kung University  Tainan Taiwan, ROC"}]},{"given":"Chun\u2010Han","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Statistics National Cheng Kung University  Tainan Taiwan, ROC"}]}],"member":"311","published-online":{"date-parts":[[2018,9,21]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/qre.858"},{"key":"e_1_2_8_3_1","volume-title":"Introduction to Statistical Quality Control","author":"Montgomery DC","year":"2009"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2016.06.037"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.2000.11980027"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/qre.1762"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.2003.11980225"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.2004.11980276"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1590\/S0103-65132007000300002"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/0740817X.2011.649386"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/qre.2101"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.2002.11980134"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-76725-1_60"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jprocont.2011.12.009"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1080\/00224065.1991.11979302"},{"key":"e_1_2_8_16_1","unstructured":"MayerD DimitriadouE HornikK WeingesselA LeischF.e1071: Misc Functions of the Department of Statistics (e1071) 2014TU Wien.
