贝叶斯估计的方差比和广义方差比
Variance Ratio and Generalized Variance Ratio of Bayes Estimates
【摘要】 用剔除数据扰动的方式,从估计效率角度讨论了数据的剔除对贝叶斯估计的影响大小,建立了判定数据影响的度量与相关系数及广义相关系数之间的等式关系,揭示了影响度量与相关性之间的内在联系。
【Abstract】 The influence of remove data on Bayes estimates is discussed in this paper from view of efficiency point by using the manner of disturbing which to remove data from the model.The equality relation between the influence measure and relevant coefficients are built and the inner relationship is revealed.
