Robust Linear Mixed Models using Hierarchical Gamma-Divergence

Shonosuke Sugasawa, Francis K. C. Hui, Alan H. Welsh

Linear mixed models (LMMs) are a popular class of methods for analyzing longitudinal and clustered data. However, such models can be sensitive to outliers, and this can lead to bia…
