Fig. 3

Distributions of long-term impact estimates (\({\widehat{{\beta }}}_{3}\)) calculated by three methods. The figure plots distributions of long-term impact estimates \({\widehat{\beta }}_{3}\) when the impact true value of long-term impact is 2. Different colors represent different models: pink represents the CSR model, red represents the OSR-ReLU model, and green represents the OSR-Sig model. The vertical black dotted line represents the true value (+ 2). The horizontal axis at the bottom of the figure indicates the axis of the parameter estimate \({\widehat{\beta }}_{3}\), and the vertical axis shows the number of parameters estimates \({\widehat{\beta }}_{3}\) in a specific interval during 1,000 simulation repetitions
