| 摘 要： | 运用差分法,得到半参数模型中参数向量和非参数向量的估计,并且当粗差的位置已经确定时,可以利用基于最小二乘原理的粗差探测方法,估计出半参数模型中的观测量所含粗差。通过算例分析,证明了算法的有效性,最后提出了粗差定位与定值时应注意的问题。

| Abstract: | In this paper,with difference method parameter and non-parametric vector estimation in semi-parametric model can be obtained.When the locations of gross errors have been identified,with the gross error detection method which is based on the least-squares principle,the gross error measurement of semi-parametric model can be estimated.After the analysis of an example,the validity of the algorithm is proved,and some points about the gross error location and evaluation which should be paid attention to are put ... |
