摘要
本文讨论了方差分量估计中必要多余观测数的确定问题,给出了计算公式,得出了在有2～3类观测值的情况下必要多余观测数应为20的结论。最后通过模拟网及实测网的计算结果,表明了本文结论的正确性。
In this paper, the definte of necessary redundancy numters in variance component estimation are discussed, and the computative formula is derived. The conclusion is, on the condifion of 2-3 kinds of measurments, the necessary redundancy numbers are 20. In the end, according to the analysical results of simulation and pratical network, these results show the Tightness of the conclusion.
