Regression on hazard ratios and cross ratios in multivariate failure time analysis
多元失效时间分析中的风险比与交叉比回归
Cox model marginal survivor function and pairwise correlation models are specified for a multivariate failure time vector. The corresponding mean and covariance structure for the cumulative baseline hazard variates and standard baseline hazard function estimators are used to develop joint estimating equations for hazard ratio and correlation parameters, in the absence of censorship. Semiparametric models for pairwise survivor functions are required to generalise these…
