Fig. 4

Result of the PD and ICE for the mass of the bat. The horizontal axis shows the mass of the bat and the vertical axis shows the predicted number of home runs per year. Dashed lines in the graph indicate the expected values. The thick blue line shows the mean relationship between the explanatory variables and the predicted values when the explanatory variables are replaced, and the blue line shows the relationship between the explanatory variables for each instance and the predicted values when the explanatory variables are replaced. The numbers on blue lines mean each instance.
