摘要
通过二步迭代和广义 Gauss- Markov定理 ,给出了三参数对数正态分布参数的一种渐近估计 .这种方法既适合于全样本场合又适合于一般缺失数据场合 .模拟结果表明
Presents approximated point estimators of three parameter log normal distributions through a two step iteration and the Gauss Markov theorem. This method is suitable not only to the complete sample case but also to the general missing data cases. The simulation example shows that the proposed approximated estimation is simple and effective to moderate and large samples.
