MCEM Algorithm of Parameters Estimation in Mixture Exponential Distribution for Constant Stress Accelerated
【摘要】 应用Monte Carlo EM(简称MCEM)加速算法改进了混合指数分布在恒加应力水平下的参数估计,并通过模拟试验说明利用Monte Carlo EM加速算法来估计混合指数分布比EM算法更有效,收敛速度更快.
【Abstract】 Monte Carlo EM algorithm is applied to present the parametric estimation of mixed exponential distribution in accelerated life-testing.Simulations are also made to show that Monte Carlo EM algorithm is more effective than EM with a fast convergence speed
