From: Optimized segmented regression models for the transition period of intervention effects
Mean squared errors under different distribution patterns of the intervention effect. The heights of the bars indicate the magnitude of the mean-squared error (MSE). The horizontal axis represents the different lengths of the transition period \(L\). Different colors represent different methods. The shaded parts of the figure represent the maximum and minimum ranges of the different methods for the corresponding MSE. When \(L=0\), the OSR model degenerates into the CSR model
