Figure 11
Three scatter plots depict holdout residuals for a RandomForest model. Each plot represents residuals for a different group: Poster, Observer, and Non-Member. The x-axis for all plots is labeled Test sample index (time order) and ranges from 0.00 to 2.00. The y-axis for each plot is labeled with the respective group's residuals: Res(Poster), Res(Observer), and Res(Non-Member). The top plot shows residuals for the Poster group, with data points at approximately (0.00, -5), (1.00, 0), and (2.00, 15). The middle plot shows residuals for the Observer group, with data points at approximately (0.00, 10), (1.00, 15), and (2.00, 30). The bottom plot shows residuals for the Non-Member group, with data points at approximately (0.00, -10), (1.00, -10), and (2.00, -40).Holdout residuals (RandomForest)
