摘要
本文建立了度量数据对Minimax线性估计及拟合值的影响的广义方差比,Cook统计量和W—K统计量。研究了他们的性质得到了一些有用的结果。并找到了W—K统计量和相关系数的关系。
In this paper, we propse the ratio of the generalized variances, Cook statistic and W—K stat is tic as tools to measure the influence of data. on the minimax linear estimator and the fitted value. Their properties werk discussed and some practical results were reached. The relation between W—K statistic and correlation coefficient was built.
