失效类型缺失的竞争风险检验札记
The modified log rank test for competing risks with missing failure type suggested by Goet-ghebeur & Ryan (1990) is derived from a partial likelihood which leaves out some information. This extra information is incorporated to give a new partial likelihood and hence a new test statistic.
平衡态循环半马尔可夫过程的逗留时间分布估计
The EM algorithm is used to develop procedures for estimating the interoccurrence distributions when n independent and identically distributed cyclic semi-Markov processes, each being ergodic, irreducible and in equilibrium, are observed over finite windows. This work is an extension of Vardi (1982a, b) who considers a similar problem for renewal processes and develops the RT algorithm for estimation of the common interoccurrence distribution. The results are illustrated…
