极大可能性估计带权解算理论及数据质量评定

Weighted Solution Theory for Maximum Possibility Estimation and Its Data Quality Evaluation

极大可能性估计是测量误差理论研究的一种新动向。针对其定权和数据质量评定问题,提出了极大可能性估计的带权解算理论,并给出了基本原理;提出了单位权模糊幅度的概念,探讨并建立了数据质量评定模型。通过实例分析,得出了与经典平差相一致的结果。

Weighted solution theory for maximum possibility estimation was put forward and its fundamental principle was given according to the problem of maximum possibility estimation,which was a new trend for research of error theory,in weight determination and data quality evaluation.Unit weight of fuzzy range was first proposed and data quality evaluation model was discussed and established.Consistent results was gotten through compared with least squares base on an example.
