加速失效时间模型的一类半参数回归方法AI 解读

In this paper a general class of nonparametric test statistics, which includes both linear and nonlinear rank tests for the accelerated failure time model, is inverted into estimating equations for multiple regression. For right-censored data this general class of semiparametric regression procedures includes the linear rank estimators of Tsiatis (1990), extends the Theil-Sen estimator based on Kendall's τ to multiple regression, and introduces several new families of…

杂论：局部依赖函数AI 解读

In the context of recent interest in extending scalar association measures to local association functions, attention is drawn to the local dependence function, the mixed partial derivative of the log density, proposed by Holland & Wang (1987). We provide an alternative motivation to that provided by Holland & Wang. We also describe a few basic properties of the local dependence function, and indicate how it may be estimated from data.
