\({\widehat{\beta }}_{3}\) and corresponding 95% CIs for all scenarios. The median of the box-and-whisker diagram is the estimated value \({\widehat{\beta }}_{3}\), and the lower and upper whiskers are the lower and upper limits of the 95% confidence interval of \({\widehat{\beta }}_{3}\), respectively. In the legend of the above figure, Estimate represents \({\widehat{\beta }}_{3}\) estimate result, and Estimate L and Estimate U represent the lower and upper limits of \({\widehat{\beta }}_{3}\) 95% CIs, respectively
