Subject | st: -xtmixed- Crossed effets & hierarchy |
Date | Thu, 2 Sep 2010 08:32:50 -0700 (PDT) |
I have estimated the following crossed random effects model: xtmixed y x1 x2 x3 || _all: R.model || quarter: mle this already worked pretty good. Now, the models are nested within brands, so i would like to add one more level to the model. Is this right like this: xtmixed y x1 x2 x3 || brand: || _all: R.model || quarter:, mle ?? The thing that confuses me is the need of the _all, R.. I dont really see what that is used for. I followed the method presented in Multilevel and Longitudunal Modeling Using Stata, Rabe-Hesketh & Skrondal, Chapter 8 Thanks in advance for any review Regards Toby Tobias Friedli Bachelor Student at the University of Zurich -- View this message in context: http://statalist.1588530.n2.nabble.com/xtmixed-Crossed-effets-hierarchy-tp5491619p5491619.html Sent from the Statalist mailing list archive at Nabble.com. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
