If all the characteristic roots are outside the unit circle, then the process is ergodic and stationary. If at least one characteristic root lies inside the unit circle, then the process is transient. AR-NN processes with characteristic roots lying on the unit circle exhibit either ergodic, random walk, or transient behavior. We also analyze the class of integrated AR-NN (ARI-NN) processes and show that a standardized ARI-NN process \u201cconverges\u201d to a Wiener process. Finally, least-squares estimation (training) of the stationary models and testing for nonstationarity is discussed. The estimators are shown to be consistent, and expressions on the limiting distributions are given. <\/jats:p>","DOI":"10.1162\/089976600300015006","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:56:30Z","timestamp":1027770990000},"page":"2427-2450","source":"Crossref","is-referenced-by-count":43,"title":["Stationary and Integrated Autoregressive Neural Network Processes"],"prefix":"10.1162","volume":"12","author":[{"given":"Adrian","family":"Trapletti","sequence":"first","affiliation":[{"name":"Department of Operations Research, Vienna University of Economics and Business Administration, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Friedrich","family":"Leisch","sequence":"additional","affiliation":[{"name":"Department of Statistics and Probability Theory, Vienna University of Technology, A-1040 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kurt","family":"Hornik","sequence":"additional","affiliation":[{"name":"Department of Statistics and Probability Theory, Vienna University of Technology, A-1040 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.2307\/3214462"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.2307\/1427125"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-9892.1985.tb00394.x"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.2307\/2951626"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-0084.1991.mp53001002.x"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-0084.1996.mp58003007.x"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1016\/0893-6080(89)90020-8"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1997.10474027"},{"key":"p_14","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1994.6.3.543"},{"key":"p_17","doi-asserted-by":"publisher","DOI":"10.1016\/0165-1889(88)90043-7"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.2307\/2297890"},{"key":"p_19","doi-asserted-by":"publisher","DOI":"10.2307\/1913237"},{"key":"p_20","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/75.2.335"},{"key":"p_21","doi-asserted-by":"publisher","DOI":"10.1016\/0304-4076(86)90039-4"},{"key":"p_22","doi-asserted-by":"publisher","DOI":"10.1016\/S0893-6080(05)80037-1"},{"key":"p_23","doi-asserted-by":"publisher","DOI":"10.2307\/1427459"},{"key":"p_25","doi-asserted-by":"publisher","DOI":"10.2307\/1425932"},{"key":"p_26","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1989.10478865"},{"key":"p_29","doi-asserted-by":"publisher","DOI":"10.2307\/1911465"}],"container-title":["Neural Computation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/089976600300015006","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:47:49Z","timestamp":1615585669000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/neco\/article\/12\/10\/2427-2450\/6412"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,10,1]]},"references-count":19,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2000,10,1]]}},"alternative-id":["10.1162\/089976600300015006"],"URL":"https:\/\/doi.org\/10.1162\/089976600300015006","relation":{},"ISSN":["0899-7667","1530-888X"],"issn-type":[{"value":"0899-7667","type":"print"},{"value":"1530-888X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,10,1]]}}}
