一元p-范极大似然平差
The Monadic p-th Norm the Maximum Likelihood Adjustment
【摘要】 本文详细推导了一元p-范极大似然平差的计算公式。在观测误差分布单峰、对称的条件下,该法可同时确定参数估值在忽略的随机性影响时,本文还推导了的估算公式。
【Abstract】 The calculating formulas of the monadic p-th norm maximum likelihood adjustment is derived. Under the assumption that the distribution of observations is unimodal and Symmetrical,this method can give the estimated values of μ,σ0, p simultaneously.A formula is also given to calculate Dμ. Two examples are presented finally. When the size of .the sample is large,the estimated values are near to their theoretical ones.
