摘要
联系参数函数不独立即联系参数间存在限制条件使得其协因数矩阵Q^x′2 秩亏及权阵P^x′2 =Q-1^x′2 不存在,扩建网极大验后估计的平差计算公式比较复杂。为简化计算方法,文中基于扩建网极大验后估计仅仅满足联系参数限制条件的原理推导了新的平差计算公式。
The functionally correlative connected parameters being equivalent to have constraints between these make that their cofactor matrix become rank defect and its Cayley inverse P′ 2 =Q -1 ′ 2 dose not exist. In this case the formulae of maximum posterior estimation are more complicate. In order to simplify this method of estimation, this paper, based on that this estimation is only satisfied with these constraints between the parameters derives a new method of maximum posterior estimation.
