September 2010 14:28 To: statalist@hsphsun2.harvard.edu Subject: st: -xtmixed- performance problem Hello everybody I want to run the following two-way error component regression in xtmixed, with cluster robust standard errors xtmixed y x1 x2 x3 x4 || _all: R.id || datevar:, mle residuals(, by(id)) Without the term residuals(,by(id)) the regression is very fast, but with the the option included, it did only 2 iterations in 48h. Does anybody have any idea, what i could do to speed the regression up? Is there maybe an option to decrease accuracy or something like that? Thank you very much for your support.
