Top $η_{G}^{2}$ effect sizes for contrasts of fixed effect estimates across model specifications/estimators

	Fixed Effect Estimates

Design Factor	X_ij (γ̂₁₀)	W_j (γ̂₀₁)	X_ijW_j (γ̂₁₁)
Contrast 1: Linear versus Logistic Model
Main Effect	0.37	0.11	0.44
× Number of Categories	0.02	0.01	0.03
× Distribution Shape	0.02	< 0.01	0.03
Contrast 2: PQL versus MLLogistic Model
Main Effect	0.06	0.03	0.07
× Size of Random Effects	0.02	0.01	0.02
× Number of Categories	0.01	< 0.01	0.01
× Cluster Size	0.01	< 0.01	0.01

Note. “×” indicates an interaction of the designated between-subjects factor of the simulation design with the within-subjects contrast for method of estimation.
