Mother-Child Interaction Effects Comparison with MENDEL, NIMA. Plots showing the comparison of EMIM and MENDEL - “option 26, Model 2: NIMA” using simulated data. A: Plot of the null model log likelihood values (with child effects fitted, but no MFG interaction effect) calculated using EMIM and MENDEL. B: Plot of the full (alternative) log likelihood values (fitting both child effects and MFG effect) calculated using EMIM and MENDEL. C: The power to detect the MFG effect for p-values of 0.05, 0.01 and 0.001. D: Plot of the MFG parameter estimates calculated using EMIM and MENDEL.
