主要借助python中的lifeline和R中的survival&survminer包实现。相关成果已发表在 Hu, Songhua, Peng Chen, and Xiaohong Chen. "Do personalized economic incentives work in promoting shared mobility? Examining customer churn using a time-varying Cox model." Transportation Research Part C: Emerging ...
In this article, following previous work of Cai and Sun, we propose a simple estimation procedure for the Cox model with time-varying coefficients based on a kernel-weighted partial likelihood approach. We construct pointwise and simultaneous confidence intervals for the regression parameters over a ...

Extensions of the Cox model have been proposed to model regression coefficients nonparametrically (Fan et al. 1997) and to allow them to be time-varying (Hastie and Tibshirani 1993; Cai and Sun 2003). In Putter et al. (2005), a Cox model was proposed for time-dependent coefficien...

Basing our analysis on a large sample of Italian firms, the probability of being uncured is here estimated with a binary logit regression, whereas a discrete time version of a Cox's proportional hazards approach is used to model the time distribution of defaults. The extension of the cure ...
