Regarding your question 2. You can use the "estimated marginal means" and "then "specify Contrasts" to get the observed differences.

These warnings are really just informations. They tell you that both your fixed factors do not very within the levels of 'codigo.de.sujeito'. So can be ignored (you could also remove these termds per hand from the random-effects part buty it would n…

Hi Alessio, Yes and no. Yes, you are totally right that the likelihoods of models fitted with REML cannot be compared to likelihoods of models with different fixed effects. This extends to AIC. But no, this also extends to the unpenalised likelihood…

If you have a factor with more than two levels (such as your color) our recommendation is that you do not interpret the estimates of the model directly (so to answer your question: you don't). This holds for both the classical (which I assume you ha…

The sum of the contrasts should to be 0. So you might want to use something like -1 in the top row, 0 in the middle row, and 1 in the bottom row. Or -0.5, -0.5, 1. Or something like that.

As the note says, the intercept corresponds to the unweighted grand mean, that is the mean of all the design cells. In your case, that is the mean of the estimated marginal means for each time point. To compare the other time points against the base…
