Testing the proportional odds model under random censoring
随机删失下比例优势模型的检验
In practical applications, it is not uncommon for the hazard functions of two groups to converge with time. One approach that allows for converging hazard functions is the proportional odds model. We develop a procedure for testing the proportional odds assumption when the available data consist of two independent random samples of randomly right‐censored lifetimes. Asymptotic normality of the test statistic is proved and the procedure is applied to two well‐known datasets.…
