A Mixture Model for Time to AIDS Data with Left Truncation and an Uncertain Origin
研究了混合模型在估计HIV感染后发展为艾滋病的概率及潜伏期分布中的应用，考虑了左截断和感染时间不确定的情况，并分析了不确定性带来的效率损失。
The use of a mixture model to estimate the probability of developing AIDS after HIV infection and the distribution of incubation time is investigated. The possibility of left truncation and an uncertain time of infection is incorporated into the analysis. The efficiency losses associated with uncertain infection times are investigated. An example is given.
