Fitting the Cox proportional hazards model to big data
AbstractThe semiparametric Cox proportional hazards model, together with the partial likelihood principle, has been widely used to study the effects of potentially time-dependent covariates on a possibly censored event time. We propose a computationally efficient method for fitting the Cox model to big data involving millions of study subjects ...

A Simple Test for the Absence of Covariate Dependence in Hazard Regression Models [PDF]
This paper extends commonly used tests for equality of hazard rates in a two-sample or k-sample setup to a situation where the covariate under study is continuous.

Testing for Proportional Hazards with Unrestricted Univariate Unobserved Heterogeneity [PDF]
We develop tests of the proportional hazards assumption, with respect to a continuous covariate, in the presence of unobserved heterogeneity with unknown distribution at the individual observation level.

The R package simPH provides tools for effectively communicating results from Cox proportional hazard (PH) models, including models with interactive and nonlinear effects. The Cox (PH) model is a popular tool for examining event data. However, previously

Unemployment Duration and its Determinants Using Cox Proportional Hazard Model Evidence from Yazd City during 2007-2010 [PDF]
The following research attempts to study the effect of personal characteristics on unemployment duration in Yazd city during 2007-2010. The Cox proportional hazard model is used to test the hypotheses in this study.

Models of Firm Dynamics and the Hazard Rate of Exits: Reconciling Theory and Evidence using Hazard Regression Models [PDF]
This paper considers empirical work relating to models of firm dynamics. We show that a hazard regression model for firm exits, with a modification to accommodate age-varying covariate effects, provides an empirical framework accommodating many of the ...
