摘要
将大地测量反演问题中的线性模型 ,综合为一般模型 ,称为反演奇异模型。运用最小二乘统一理论给出了反演奇异模型的参数和单位权方差通用估计公式 ,给出了这种模型的验前验后方差一致性检验方法。
The general model called as a inversion singular model is synthesized from the linear models in geodesy inversion.On the basis of the least square unified theory we give the universal formulae for the estimation of the parameters and unit weight variance of the singular model and the test method of the consistency between the priori and posteriori variances of this model.Finally,the inversion parameter estimation is also discussed.
