Estimation in Cox proportional hazards model with heteroscedastic errors in covariates

Modern Stochastics: Theory and Applications
Consistent estimators of the baseline hazard rate and the regression parameter are constructed in the Cox proportional hazards model with heteroscedastic measurement errors, assuming that the baseline hazard function belongs to a certain class of ...

Regularization Paths for Cox's Proportional Hazards Model via Coordinate Descent [PDF]

We introduce a pathwise algorithm for the Cox proportional hazards model, regularized by convex combinations of l_1 and l_2 penalties (elastic net). Our algorithm fits via cyclical coordinate descent, and employs warm starts to find a solution along a ...

Semiparametric estimation of a panel data proportional hazards model with fixed effects [PDF]

This paper considers a panel duration model that has a proportional hazards specification with fixed effects. The paper shows how to estimate the baseline and integrated baseline hazard functions without assuming that they belong to known ...

A shared frailty semi-parametric markov renewal model for travel and activity time-use pattern analysis [PDF]

This study investigates the influence of observed explanatory factors and unobserved random effect (heterogeneity) on episode durations of travel-activity chain.

It's the economy stupid: comparison of proportional hazards models with economic and socio-demographic variables for estimating the purchase of financial products

, 2005
Relatively there is little empirical research that has been taken to understand how the underlying economy affects customers’ subsequent financial product purchase behaviours.

Estimating a semi-parametric duration model without specifying heterogeneity [PDF]

This paper presents a new estimator for the mixed proportional hazard model that allows for a nonparametric baseline hazard and time-varying regressors.
