 从测量误差的实际情况出发,提出一元非对称P范分布极大似然平差方法,建立该方法的数学模型,得到一元非对称P范分布的密度函数,利用极大似然估计方法推导参数估计值的基础方程。研究表明,结合实际测量数据,通过选择合适的参数估计值,可以增加误差分布模型选取的灵活性,便于P范分布理论在测绘数据处理中的推广应用。 更多还原

【Abstract】 According to the foundational properties of the random errors,this paper deduces a more general error distribution—the unsymmetrical P-norm distribution,and then discusses the maximum likelihood adjustment of the p-norm distribution in detail.The distributions of degenerate,Laplace,normal and rectangular are the specific cases of the unsymmetrical P-norm distribution respectively.The maximum likelihood adjustment method of the unsymmetrical P-norm distribution is proposed,and the foundational eq... 更多还原
