摘要
详细推导了加权线性回归诊断中h_(ii)的统计分布,针对G-M模型与线性回归模型的差异,指出测量数据处理中,使用的统计量h_(ii)的不合理性,给出了适于测量数据诊断的公式,并以数字实例加以分析和说明。
In this paper, the statistical distribution for hii of linear regression diagnosis with weight are derived in detail. Aiming at the differences between the G-M model and model of linear regression, the statistic hii is not suitable for surveying data processing, the correct formula are given, and the numerical examples are analysed and explained.
