Additive Functional Cox Model. [PDF]

open access: yesJ Comput Graph Stat, 2021
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 ...

The Change-Plane Cox Model. [PDF]

open access: yesBiometrika, 2018
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 ...

Comparison of survival prediction models for pancreatic cancer: Cox model versus machine learning models. [PDF]

open access: yesGenomics Inform, 2022
A survival prediction model has recently been developed to evaluate the prognosis of resected nonmetastatic pancreatic ductal adenocarcinoma based on a Cox model using two nationwide databases: Surveillance, Epidemiology and End Results (SEER) and Korea ...

ODACH: a one-shot distributed algorithm for Cox model with heterogeneous multi-center data. [PDF]

open access: yesSci Rep, 2022
We developed a One-shot Distributed Algorithm for Cox proportional-hazards model to analyze Heterogeneous multi-center time-to-event data (ODACH) circumventing the need for sharing patient-level information across sites.

Optimal Estimation for the Functional Cox Model [PDF]

open access: yes, 2016
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

MODEL REGRESI COX PROPORSIONAL HAZARD PADA DATA KETAHANAN HIDUP [PDF]

open access: yesMedia Statistika, 2013
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]

open access: yesRevista Panamericana de Salud Pública, 2022
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 ...
