Hi R users!
I am trying to learn some multilevel analysis, but unfortunately i am now very
confused. The reason:
http://www.ats.ucla.edu/stat/hlm/seminars/hlm_mlm/mlm_hlm_seminar.htm
http://www.ats.ucla.edu/stat/sas/seminars/sas_mlm/mlm_sas_seminar.htm
and
MlmSoftRev. pdf from mlmRev package.

Am i mistaken somehow? If not, could they both be valid models (i presume) but
each showing something else, in terms of connections between this variables?
Thank you and sorry for taking up your time.
