Thank you very much Chris, but I am not sure if MLM could be used. I "knew" that MLM relies in the a priori specification of the different groups, and in my case the hospitals with "growing admission" and "stable admissions" are not specified. Am I correct?? Or I need to classify hospitals in "growing admission" and "stable admissions" before MLM analisys.

Thanks a lot

Longitudinal MLM would be the most appropriate choice, observations (timepts) nested within cities. Will give equivalent results to LGM at most basic level.

Subject: Question about analysis of longitudinal data

Hello everybody!! I'm asking for your kind advice because I have a consolidated weekly data of hospital admissions for the las 2 years (104 observation points) of 32 cities. I'm looking to estimate the mean growth of hospital admissions over this period, but a visual inspection of the data suggest that some cities shows a growth in hospital admission but others has stable records over time (admissions did not vary over time)

My first idea was use LGM, but i have no access to Mplus or Lisrel (I have no licence of this packages), so I want tos ask you suggest me any idea for analyse this set.

Any help or reference will be gratefully received.

Kind Regards

Norberto
