摘要
建立了边界条件下线性模型中的Cook距离,W—K统计量和A—P统计量。用它们研究了数据对约束最小二乘估计及拟合值的影响问题,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 estimate and the fitted value. Some meaning results are reached.
