Belle: Before I provide any more help, you'll need to follow some posting guide rules and describe what you have done with some R code, describe what the problem is, and describe what you are hoping to accomplish.
The fact that the results you get from R and SAS are different doesn't mean there is a problem. If you can provide more details on what you are doing, what hasn't worked (specifically), then you will also find others on this list will provide help too. > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of Belle > Sent: Thursday, January 27, 2011 3:54 PM > To: r-help@r-project.org > Subject: Re: [R] HLM Model > > > Hi Harold: > > Yes, this was the R code that I tried, and got different result from SAS. > > Is that mean I cannot actually use R to run unstructured covariance matrix? > How can I solve this problem if I need an unstructured covariance matrix > method? > > Thanks for the help. > -- > View this message in context: http://r.789695.n4.nabble.com/HLM-Model- > tp3242999p3243158.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
