一种新的方差检验模型在GPS网基准点兼容性分析中的应用

The Application of a Novel Variance Testing Model for Compatibility Analysis of Datum Points in Engineering GPS Network

  • 摘要: 在分析已有的单位权方差假设检验法基础上,讨论了基于单位权方差比构造统计量的方法,进而提出了一种新的适用于工程GPS网基准点兼容性分析的单位权方差假设检验模型,简称方差检验模型。利用算例验证了新模型的可行性和有效性。

     

    Abstract: A question that 'Is the approach to construction statistics reasonable in the existed unit weight variance hypothesis testing method?' was proposed and two specific reasons were given in this paper.After approaches to construction statistics deeply discussed based on unit weight variance ratio,a novel approach to construction statistics for global testing was put forward.An approach to construction statistics based on try method for local testing was analyzed and then it's scope and inadequate of application was given,furthermore,a novel approach based on search-try method was put forward.And then,a novel unit weight variance hypothesis testing model was developed which was applied to compatibility analysis of single or multiple incompatibility datum points in engineering GPS network.Finally,it verifies that the novel model is feasible and effective via an example in this paper.
