LMER vs PROC MIXED estimates
Hi experts,
I have just about started to use R (after using SAS for more than 5 years)
and still finding my way...I have been trying to replicate PROC MIXED
results in LMER but noticed that the estimates are coming different.
My SAS code is as follows (trying to randomise X2 and Intercept):
PROC MIXED DATA = <DATASET NAME> NAMELEN=100 METHOD=REML MAXITER=1000;
CLASS GEOGRAPHY;
MODEL y

standardized random effects with ranef.lme()
Using ranef() (package nlme, version 3.1-75) with an 'lme' object I can
obtain random effects for intercept and slope of a certain level (say:
1) - this corresponds to (say level 1) "residuals" in MLWin. Maybe I'm
mistaken here, but the results are identical.
However, if I try to get the standardized random effects adding the
paramter "standard=T" to the
