Both specifications are the same model. An intercept is added by default unless you use +0 or -1 like ~0 + LEAD|GRP or ~ -1 + LEAD|GRP ________________________________________ Van: r-help-boun...@r-project.org [r-help-boun...@r-project.org] namens YA [xinxi...@163.com] Verzonden: zaterdag 14 april 2012 18:33 Aan: r-help@r-project.org Onderwerp: [R] quick question about lme()
Hi everyone, I have a quick question about the random part in lme(). Here is the code: > lme(WBEING~HRS+LEAD+G.HRS,random=~LEAD|GRP) I want to specify both random intercept and random slope of LEAD. Is the random intercept already in it? or should I specify it like: > lme(WBEING~HRS+LEAD+G.HRS,random=~1+LEAD|GRP) ? Thank you very much.
