Regression analysis of life tables and related nonparametric tests

摘要: Cox (1972) proposed a regression model for life tables and derived certain hypothesis testing procedures. If there is no censoring we wish to test simple null hypothesis, his statistic similar permutation test. This relation explored it shown how modify any rank allow censored data. Cox's the log are compared concluded that if occurs nonparametric be preferred sample size very small. When tests like recommended.
