Proportional hazards models with continuous marks [PDF]

open access: yesThe Annals of Statistics, 2009
For time-to-event data with finitely many competing risks, the proportional hazards model has been a popular tool for relating the cause-specific outcomes to covariates [Prentice et al. Biometrics 34 (1978) 541--554]. This article studies an extension of this approach to allow a continuum of competing risks, in which the cause of failure is replaced by

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

open access: yesJournal of Statistical Software, 2011
We introduce a pathwise algorithm for the Cox proportional hazards model, regularized by convex combinations of l1 and l2 penalties (elastic net). Our algorithm fits via cyclical coordinate descent, and employs warm starts to find a solution along a ...

Accurate training of the Cox proportional hazards model on vertically-partitioned data while preserving privacy [PDF]

open access: yesBMC Medical Informatics and Decision Making, 2022
Background Analysing distributed medical data is challenging because of data sensitivity and various regulations to access and combine data. Some privacy-preserving methods are known for analyzing horizontally-partitioned data, where different ...

Duration Time-Series Models With Proportional Hazard [PDF]

open access: greenJournal of Time Series Analysis, 2007
Abstract. The analysis of liquidity in financial markets is generally performed by means of the dynamics of the observed intertrade durations (possibly weighted by price or volume). Various dynamic models for duration data have been considered in the literature, such as the Autoregressive Conditional Duration (ACD) model.

Statistical estimation in the proportional hazards model with risk set sampling [PDF]

open access: green, 2004
Thomas' partial likelihood estimator of regression parameters is widely used in the analysis of nested case-control data with Cox's model. This paper proposes a new estimator of the regression parameters, which is consistent and asymptotically normal ...

Does the Tax Cuts Policy Lower Firm Survival Risk? Evidence from China [PDF]

open access: yesE3S Web of Conferences, 2023
This paper examines the effect of tax cuts policy on firm survival risk. We analyze a panel data of China’s listed companies over the period 20082021 based on two different techniques: Kaplan-Meier survival estimator and the Cox proportional hazards ...

Using Wavelet Shrinkage in the Cox Proportional Hazards Regression model (simulation study) [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2022
The proposed method in this paper dealt with the problem of data contamination in the Cox Proportional Hazards Regression model (CPHRM) by using Wavelet Shrinkage to de-noise data, calculating the discrete wavelet transformation coefficients for wavelets
