一种估计粗差大小的新方法——先验方差待定参数法
Abstract：In this paper, we introduce a new method, prior-variance undecided parameter method (PVUP), to estimate gross errors using prior variance without Least-Square or hypothesis testing. Starting with fundamental principles, we give the model of this method next. Last, we demonstrate its simplicity and validity using some examples compared with other methods, such as QUAD.
