Estimation procedures for the susceptibilities and infectivities are derived for three sets of data: complete data, meaning that the whole epidemic process is observed continuously; the removal processes are observed continuously; only the final state is observed. Under the assumption of a major outbreak in a population of size n it is shown that, for all three data sets, the susceptibility estimators are always efficient, i.e. consistent with a \u221an rate of convergence. The infectivity estimators are \u2018in most cases\u2019 respectively efficient, efficient and unidentifiable. However, if some susceptibilities are equal then the corresponding infectivity estimators are respectively barely consistent (\u221alog(n) rate of convergence), not consistent and unidentifiable. The estimators are applied to simulated data.<\/jats:p>","DOI":"10.1111\/1467-9868.00147","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T19:35:17Z","timestamp":1047497717000},"page":"663-679","source":"Crossref","is-referenced-by-count":17,"title":["Estimation in Multitype Epidemics"],"prefix":"10.1093","volume":"60","author":[{"given":"Tom","family":"Britton","sequence":"first","affiliation":[{"name":"La Trobe University , Bundoora , Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2002,1,6]]},"container-title":["Journal of the Royal Statistical Society Series B: Statistical Methodology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1467-9868.00147","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/academic.oup.com\/jrsssb\/article-pdf\/60\/4\/663\/49589039\/jrsssb_60_4_663.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jrsssb\/article-pdf\/60\/4\/663\/49589039\/jrsssb_60_4_663.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,3,22]],"date-time":"2023-03-22T05:20:44Z","timestamp":1679462444000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jrsssb\/article\/60\/4\/663\/7083102"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,11,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2002,1,6]]},"published-print":{"date-parts":[[1998,11,1]]}},"URL":"https:\/\/doi.org\/10.1111\/1467-9868.00147","relation":{},"ISSN":["1369-7412","1467-9868"],"issn-type":[{"value":"1369-7412","type":"print"},{"value":"1467-9868","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1998,11]]},"published":{"date-parts":[[1998,11,1]]}}}
