A Simple Test for the Absence of Covariate Dependence in Hazard Regression Models [PDF]

open access: yes, 2004
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.

Generalized log-logistic proportional hazard model with applications in survival analysis

open access: yesJournal of Statistical Distributions and Applications, 2016
Proportional hazard (PH) models can be formulated with or without assuming a probability distribution for survival times. The former assumption leads to parametric models, whereas the latter leads to the semi-parametric Cox model which is by far the most

Hazard regression model and cure rate model in colon cancer relative survival trends: are they telling the same story?

open access: yes, 2008
Hazard regression models and cure rate models can be advantageously used in cancer relative survival analysis. We explored the advantages and limits of these two models in colon cancer and focused on the prognostic impact of the year of diagnosis on ...

Application of Proportional Hazard and Additive Models in the Survival Analysis of Breast Cancer Patients

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
Breast cancer is the most common type of cancer among women and one of the highest causes of death among other types of cancer. This study aims to evaluate the methodological advantages of additive hazard models over the multiplicative Cox model in ...

An Assessment of the Cox Proportional Hazards Regression Model for Epidemiologic Studies

open access: yesRisk Analysis, 2018
The basic assumptions of the Cox proportional hazards regression model are rarely questioned. This study addresses whether hazard ratio, i.e., relative risk (RR), estimates using the Cox model are biased when these assumptions are violated.
