[問題] 一題MLE的問題 ~消失
A random variable X is said to have a lognormal distribution,if the logarithm
of X has a normal distribution.Let X1,X2,...,Xn be iid lognormal random
variables ,thus Yi=lnXi ~N(μ,σ^2).Use invariance principle of maximum
likelihood estimation to find the MLE of E(Xi) and Var(Xi).
有誰知道怎麼解的,回答一下..thx
