I Describe how to estimate the mean response, for particular values of the covariates. I Given the height and diameter, can we predict the volume of a cherry tree? E.g.if a particular tree has diameter 11 inches and height 85 feet, can we predict its volume? I What is the average volume of all cherry trees having a given height and diameter? E.g. if we consider every cherry tree with diameter 11 inches and height 85 feet, can we estimate their mean volume?","PeriodicalId":403209,"journal":{"name":"The Clinician’s Guide to Alcohol Moderation","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116849647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
