| 摘 要： | 论述了模型误差影响参数估值的一些理论问题,指出了随机模型误差和函数模型误差之间的相互作用和转化。为讨论平差系统最优模型的选取,给出了与现有文献将模型误差纳入平差系统的思路不同的一个估计和识别模型误差的理论基础公式,由此导出了相应的实用公式,给出了平差系统模型的优选方法。

| Abstract: | The estimated value of parameters' is optimized and unbias only if the error of ad-justment model is not outstanding. Some theory problems affecting parameters estimation are discussed in this paper. Influence and transformation between errors of stochastic and functional models is pointed out as well. For choosing the best adjustment model, a theory formula, which is different from the methods in existing literatures, used to estimate and identify model error is proposed by the author. Based on that theory formula, an applied one and a method of selecting the best model of adjustment system are given. |
