Multilevel logistic regression using lmer vs glmmPQL vs. gllamm in Stata
Dear all, I am trying to replicate some multilevel models with binary outcomes using R's "lmer" and "glmmPQL" and Stata's gllmm, respectively. The data can be found at <http://www.uni-koeln.de/~ahf34/xerop.dta>. The relevant Stata output can be found at <http://www.uni- koeln.de/~ahf34/stataoutput.txt>. First, you will find the unconditional model, i.e. no level1- or 2-predictor variables. The second model contains some level 1-predictor variables My R file can be found at <ht...

barchart in lattice
...fferent panels and within each panel a barchart of 'country'. barchart(daten$COUNTRY|daten$STATUS), barchart(table(daten$COUNTRY)|table(daten$STATUS)), etc. are obviously wrong. I have absolutely no idea how to do this.
