The data deletion model and the mean drift model are equivalent in a general linear regression model.
为了诊断具有异方差的线性回归模型的异常点，建立了具有异方差的均值漂移模型和数据删除模型。
This model has nonlinear drift, has significant mean-reverting effect, and the volatility is highly sensitive to interest level.
此模型的漂移项为非线性形式，具有显著的均值回复效应，且利率波动对利率水平极为敏感。
