摘要
本文从方向导数的角度分析了极大似然估计法,提出了方向极大似然估计的概念,并在正态分布下,指出μ与σ服从等轴双曲线型关系.
In this paper, by analysing maximum likelihood Estemate Method on Directional derivative, a new concept-Directional Maximum likelihood Estemate has been ab-tained and thus the hyperbola relation between μ and σ has been confimed according to this concept and the supposition of Normal distribution.
