摘要
给出对数正态分布的几个性质,分别利用矩估计法和最大似然估计法求出对数正态分布参数的点估计,并讨论其参数的区间估计。
This paper proposes several properties of the lognormal distribution and then derives point estimation of its parameters by using moment estimation and maximum likelihood estimation respectively.The paper also demonstrates interval estimation of its parameters.
