Observational studies are common in most fields that study the effects of treatments on people.\u003cbr\u003eThe second edition of Observational Studies is about 50% longer than the first edition, with many new examples and methods. There are new chapters on nonadditive models for treatment effects (5) and planning observational studies     , and the chapter on coherence (9) has been extensively rewritten.\u003cbr\u003ePaul R. Rosenbaum is Robert G. Putzel Professor, Department of Statistics, The Wharton School of the University of Pennsylvania. He is a fellow of the American Statistical Association.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2002-01-08\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9780387989679\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-1-4757-3692-2\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 377\u003c\/p\u003e ","brand":"Springer New York","offers":[{"title":"Default Title","offer_id":44343429529740,"sku":"9780387989679","price":251.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9780387989679.jpg?v=1775710829","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9780387989679","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
