Although many variable selection procedures have been developed for Coxs proportional hazard model, the study of such models with time-varying coefficients appears to be limited. The variable selection methods involving nonconvex penalty function, such as the minimax concave penalty (MCP), introduces ...
A Flexible Approach to Time-varying Coefficients in the Cox Regression Setting Research on methods for studying time-to-event data (survival analysis) has been extensive in recent years. The basic model in use today represents the haz... Daniel,J.,Sargent - 《Lifetime Data Analysis》 被引量...

The Cox model with time-dependent coefficients has been studied by a number of authors recently. In this paper, we develop empirical likelihood (EL) pointwise confidence regions for the time-dependent regression coefficients via local partial likelihood smoothing. The EL simultaneous confidence bands fo...
We focus on Cox models with time-varying coefficients. The theoretical results on variable selection can be extended easily to some other important models which we only mention briefly since they can be treated in the same way. The models considered here are the most popular among structured ...
Finally, there is much more to Carstensen’s note than I have presented. He goes on to provide a fairly complete analysis of the lung data while looking at cumulative rates, survival, practical time splitting, time varying coefficients and more ideas along the way. ...
