摘要
对多元约束线性回归模型 ,本文讨论了约束最小二乘估计的影响问题 ,定义了度量影响的多元约束Cook距离和多元约束 W- K统计量 ,给出了其分布 ,建立了约束 W- K统计量与约束广义相关系数之间的联系。
In this paper,the influence of the least squares estimates for the multivariate linear regression models under the restricted conditions is discussed,and multivariate restricted W K distance and Cook distance is defined as measures of influence.Their distributions are given,and the relationships between the restricted W K distances and the generalized correlation coefficients are also established.
