概括平差模型及其方差的区间估计和假设检验

摘要

The article distinguished two different types data in control network,and establishded error equation and reference equation by observation data and baseline data in the controlling network,and then established a generalization adjustment model.Interval estimation of variance and hypothesis testing of reference equations were calculated by mathe-matical statistics,and finally they were applied with the selection of baseline data in combined network.A useful conclu-sions was obtained.%文章区分了控制网中的两类不同性质的数据，通过控制网中的观测数据和基准数据分别建立了误差方程和基准方程，从而建立了概括平差模型。应用数理统计计算了方差的区间估计和基准方程的假设检验，最后应用于附合网基准数据选用的判断，得出了有益的结论。
