SEM mediation analysis parameter estimates

Fig. 3. Each data point represents the standardized indirect (X-axis) and standardized direct (Y-axis) effects of the president's party on IMR, WIMR, or BIMR retrieved from a model each time a given rotating variable was selected into the model. The variables that mediate the effect of the president's party on IMRs can be identified as the president's party indirect effects increase while direct effects decrease. These variables appear in clusters located at the lower-right quadrant of the scatterplots. Standardized coefficients are comparable within panels but not between panels, as coefficients are standardized using the standard deviation of the respective dependent variable (and SD_IMR$\ne$ SD_WMR$\ne$SD_BMR).
