摘要 文中应用Monte Carlo EM加速算法(简称MCEM加速算法),给出了对数正态分布的参数估计问题,并进行模拟试验,说明利用Monte Carlo EM加速算法来估计对数正态分布比EM算法更有效,收敛速度更快。 Monte Carlo EM algorithm is applied to solve parametric estimation of logarithmic normal distribution.Simulations show that Monte Carlo EM algorithm is more effective than EM with a fast convergence.
