Additive Functional Cox Model. [PDF]
We propose the Additive Functional Cox Model to flexibly quantify the association between functional covariates and time to event data. The model extends the linear functional proportional hazards model by allowing the association between the functional covariate and log hazard to vary non-linearly in both the functional domain and the value of the ...

A Non‐stationary Cox Model [PDF]
The purpose of this paper is to consider the problem of statistical inference about a hazard rate function that is specified as the product of a parametric regression part and a non‐parametric baseline hazard. Unlike Cox's proportional hazard model, the baseline hazard not only depends on the duration variable, but also on the starting date of the ...

Optimal Estimation for the Functional Cox Model
Functional covariates are common in many medical, biodemographic, and neuroimaging studies. The aim of this paper is to study functional Cox models with right-censored data in the presence of both functional and scalar covariates. We study the asymptotic

The Change-Plane Cox Model. [PDF]
We propose a projection pursuit technique in survival analysis for finding lower-dimensional projections that exhibit differentiated survival outcome. This idea is formally introduced as the change-plane Cox model, a non-regular Cox model with a change-plane in the covariate space dividing the population into two subgroups whose hazards are ...

Asymptotic theory for the Cox model with missing time-dependent covariate [PDF]
The relationship between a time-dependent covariate and survival times is usually evaluated via the Cox model. Time-dependent covariates are generally available as longitudinal data collected regularly during the course of the study.

MODEL REGRESI COX PROPORSIONAL HAZARD PADA DATA KETAHANAN HIDUP [PDF]
A lot of events occured in daily life are connected with survival time, for example a time interval that measure the failure of a product, time duration which is needed to recover from disease, the back pain recurred after treatment.

Cox model and decision trees: an application to breast cancer data [PDF]
Objective. To evaluate, using semiparametric methodologies of survival analysis, the relationship between covariates and time to death of patients with breast cancer, as well as the determination discriminatory power in the conditional inference tree of ...

Random survival forest in determination of important risk factors on overall survival and disease-free survival in gastric cancer patients [PDF]
Objective: Although the incidence of stomach cancer is decreasing in the world, its incidence is still high in Iran. Despite different treatments for cancer, disease recurrence, and death may occur in some patients.

The Impact of the EU Enlargement on the Speed of Decision-Making [PDF]
This paper presents a quantitative empirical study of the impact of the EU enlargements in 1995 and 2004 on the speed of the decision-making process (legislative process).
