The data deletion model and the mean drift model are equivalent in a general linear regression model. This paper uses the theory of least squares to extend the equivalence for the linear model with additional information.

• 在普通的线性回归模型中；数据删除模型与均值漂移模型是具有等价性的；文章利用线性模型的最小二乘参数估计方法；将此等价性推广至具有附加信息的线性模型中.
