If it turns out to be non-significant or does not seem to add much to the model's explanatory power, then it can be dropped. This type of multilevel model is referred to as a disaggregated model for multilevel data. In multinomial logistic regression you can also consider measures that are similar to R 2 in ordinary least-squares linear regression, which is the proportion of variance that can be explained by the model. Multiple regression analysis is a powerful technique used for predicting the unknown value of a variable from the known value of two or more variables- also called the predictors. Mixed models contain both fixed effects analogous to the coefficients in standard regression models and random effects not directly estimated but instead summarized through the unique elements of their variance-covariance matrix.
