Comparison of some R^2 as measures of goodness of fit in linear mixed models
A simulation study was conducted to evaluate and compare the R^2 statistics proposed together with other R^2 statistics reported in the literature. Finally, the studied R^2 statistics are illustrated using real data. In conclusion, the two proposed R^2 statistics have the following properties: intuitive interpretation, well defined range and they can be interpreted in an absolute scale without doing reference to a null model. However, the simulation study evidences that, as well as other R^2 statistics, the two proposed R^2 statistics sometimes are not able to discriminate when the removed variables from the model are important.
