| 摘 要： | 由于观测条件的变化，观测值方差将产生随机波动。本文根据Ｂａｙｅｓ估计理论，推导了线性模型待估参数的分布函数及观测值方差估计公式，并将其用于位移检验。计算结果表明，在同样的置信度下，本方法更符合实际。文中还对参数估值的统计性质进行了讨论。

| Abstract: | Based on Bayes analysis theory,a Bayes statistical test method is proposed for deformation analysis,the distributive function of parameter to be estimated in linear model and the estimation formulae of variance are derived.They are used in displacement test and the results show that the new method is dependable for distinguishing deformation.In addition,the statistical characters of estimated parameters are discussed in this paper. |
