摘　　要：本文建立了边界条件下度量数据影响的Cook距离。W-K统计量和A-P统计量。计论了它们的统计性质,并用它们研究了数据对边界约束最小二乘估计及拟合值的影响,得到了一些有意义的结果。In this paper, we construct Cook distance W-K and A-P statistics in the side-constrained least square estimate and use them to study the influence of data on the side-constrained least square and on the fitted value. Some meaning results arc reached.

关 键 词：线性回归 COOK距离 W-K统计量
