摘要
讨论了椭球约束下协方差阵扰动模型和数据删除模型对线性回归参数的影响问题,给出了在椭球约束下G-M模型与椭球约束下一般线性模型及在椭球约束下数据删除模型中回归参数的估计之间的关系。
In this paper,we study the issue of the influence with covariance matrix disturbing model and data missing data.The relationship of the regression parameter among some linear models with respect to ellipsoidal restricted conditions,such as G-M model,deneralized linear model and linear model with deleted data,is made explicitly.
