Robustness and balance in the mixed model.
When balanced data are analyzed by a robust method, different weights are applied to data points depending on their apparent status as outliers. This results in the effective unbalancing of the data. Concepts developed for the analysis of unbalanced data can help to suggest robust methods of analysis for balanced data.
