Coxian phase-type models have the finite-jump property while the joint models usually assume a continuous variation. The gap between continuity and discreteness makes the two models rarely used together. In this paper, a partition-based approach is proposed to jointly model the charge accumulation process and the time to discharge. The key construction of our new approach is a set of partition cells with their boundaries determined by a family of differential equations. Using the cells, our new approach makes it possible to incorporate finite jumps induced by a Coxian phase-type model into the charge accumulation process, therefore taking advantage of both the Coxian phase-type models and joint models. As a benefit, a couple of measures of the \u201ccost\u201d of staying in each medical stage (identified with phases of a Coxian phase-type model) are derived, which cannot be approached without considering the joint models and the Coxian phase-type models together. A two-step procedure is provided to generate consistent estimation of model parameters, which is applied to a subsample drawn from a well-known medical cost database.<\/jats:p>","DOI":"10.1155\/2018\/6367243","type":"journal-article","created":{"date-parts":[[2018,6,10]],"date-time":"2018-06-10T19:32:28Z","timestamp":1528659148000},"page":"1-13","source":"Crossref","is-referenced-by-count":2,"title":["Understanding Dynamic Status Change of Hospital Stay and Cost Accumulation via Combining Continuous and Finitely Jumped Processes"],"prefix":"10.1155","volume":"2018","author":[{"given":"Yanqiao","family":"Zheng","sequence":"first","affiliation":[{"name":"School of Finance, Zhejiang University of Finance and Economics, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaobing","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Data Sciences, Zhejiang University of Finance and Economics, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4708-2854","authenticated-orcid":true,"given":"Xiaoqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Finance, Zhejiang University of Finance and Economics, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"12","key":"6","first-page":"197","volume":"340","year":"1996","journal-title":"Medical Care"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1177\/0272989X98018002S07"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.2307\/2533947"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1524-4733.2008.00421.x"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2728"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/s10729-005-2012-z"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1023\/A:1020394525938"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s10729-008-9070-y"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2014.01.063"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.25.0654"},{"issue":"3","key":"21","first-page":"809","volume":"14","year":"2004","journal-title":"Statistica Sinica"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1093\/biostatistics\/1.4.465"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1080\/15598608.2013.772036"},{"issue":"1","key":"19","first-page":"57","volume":"9","year":"2011","journal-title":"Revstat Statistical Journal"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1002\/sim.6141"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1023\/A:1024264224760"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2484"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1002\/hec.774"},{"year":"2010","key":"1"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2018\/6367243.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2018\/6367243.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2018\/6367243.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,6,10]],"date-time":"2018-06-10T19:32:38Z","timestamp":1528659158000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/cmmm\/2018\/6367243\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,6,10]]},"references-count":19,"alternative-id":["6367243","6367243"],"URL":"https:\/\/doi.org\/10.1155\/2018\/6367243","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"type":"print","value":"1748-670X"},{"type":"electronic","value":"1748-6718"}],"subject":[],"published":{"date-parts":[[2018,6,10]]}}}
