Dear All, 

I have one  doubt and I think you can help me. I am a Phd student and I have conducted one mix-model analysis using the command  xtmixed to analyze associations over 3 years of data. so I have  xi: xtmixed ....  || codigo: i.year, covariance(identity). So my question is can I interpret the coefficient as I interpret it in a linear regression? For example if I increase  one unit in my exposure the outcome will change Coef. over time? Or I should only  say that exposure and outcome are associated and in each direction, over time. 

thank you so much
regards 

Luisa
