Hello,
I have data with 2 random variables and I would like to analyse them with a mixed-effects model (on Matlab). I want to make some regressions between fixed variables of my model.
I've aleady tried the fitlme function of the linear mixed model, but I am not sure if really this function is an equivalent of polyfit function in simple linear models. And if so, how to get the coefficient and the plot of the correlation ?
Could someone help me on this ?
Thank you in advence.

Take a look at
http://mathworks.com/help/stats/mixed-effects-models.html
You get the correlation from the output Psi, which is the estimated covariance matrix of the random effects.
