An exact corrected log-likelihood function for Cox's proportional hazards model under measurement error and some extensions [PDF]
This paper studies Cox`s proportional hazards model under covariate measurement error. Nakamura`s (1990) methodology of corrected log-likelihood will be applied to the so called Breslow likelihood, which is, in the absence of measurement error ...

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

Limit Theorems for a Cox-Ingersoll-Ross Process with Hawkes Jumps [PDF]
In this paper, we propose a stochastic process, which is a Cox-Ingersoll-Ross process with Hawkes jumps. It can be seen as a generalization of the classical Cox-Ingersoll-Ross process and the classical Hawkes process with exponential exciting function ...

Quasi-linear Cox proportional hazards model with cross- L1 penalty
Background To accurately predict the response to treatment, we need a stable and effective risk score that can be calculated from patient characteristics.

Extreme learning machine Cox model for high‐dimensional survival analysis
Some interesting recent studies have shown that neural network models are useful alternatives in modeling survival data when the assumptions of a classical parametric or semiparametric survival model such as the Cox (1972) model are seriously violated ...

Change detection in the Cox-Ingersoll-Ross model [PDF]
We propose a change detection method for the famous Cox--Ingersoll--Ross model. This model is widely used in financial mathematics and therefore detecting a change in its parameters is of crucial importance.

Background and Objectives: In survival analysis, using the Cox model to determine the effective factors requires the assumptions whose failure of leads to biased results.
