摘要
本文按尘肺病的进期、死亡过程构造了一个含有三个暂态和两个吸收态的多状态模型,叙述了模型参数的估计、进期率和生存率等评价指标的计算。利用此模型分析了淮北煤矿2906例尘肺病人的随访资料,揭示了尘肺病的发展规律,显示了多状态模型分析的优越性。
A statistical modal was deviced for analysing the data involving three transient disease and two absorbing death states of patients suffering from pneumo-coniosis. Using this modal, the data of 2 906 patients registered since 1949 were analyzed. More meanful results were obtained.
