一种特殊混合分布的参数估计

Estimation of parameters of a special mixed distribution

混合分布是寿命数据分析中的重要的统计模型.讨论一种寿命实验条件下特殊混合分布模型的参数估计.在寿命试验中,应用EM算法计算出了在完全数据场合和截尾数据场合下的的参数估计.

Mixed distribution plays an important role in life time data analysis. This paper deals with the parameter estimation of a special mixed distribution under the life time test. The parameter estimation of the situation of full data and the situation of tail cutting is stidied with the EM algorithm under the life time test.
