Elimination of Causes in Competing Risks: A Hazards Model Approach
نویسندگان
چکیده
The problem concerning elimination of causes and its impact has been a longstanding problem in the field of survival analysis. In this paper, a covariate dependent model based on proportional hazards has been proposed. In addition, a test procedure is suggested for testing the independence of competing risks based on Islam [1, 2]. The estimation and test procedures are applied to analyze the competing causes in maternal morbidity data from Bangladesh. The results confirm that although there are slight changes in the estimates for before and after elimination of causes, the competing causes satisfy independence hypothesis.

Comparison of Random Survival Forests for Competing Risks and Regression Models in Determining Mortality Risk Factors in Breast Cancer Patients in Mahdieh Center, Hamedan, Iran
Introduction: Breast cancer is one of the most common cancers among women worldwide. Patients with cancer may die due to disease progression or other types of events. These different event types are called competing risks. This study aimed to determine the factors affecting the survival of patients with breast cancer using three different approaches: cause-specific hazards regression, subdistri...
متن کاملParametric Estimation in a Recurrent Competing Risks Model
A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...

Background and purpose: Mortality is a natural and critical event and always has been intentioned as a biological, demographic, social and economic phenomenon. One of the dimensions of mortality reviewing is checking causes of death and determining life expectancy. Some causes of death lead to severe reduction in life expectancy. In this survey, the value of gain in life expectancy of 28 pro...
متن کاملMethods of competing risks analysis of end-stage renal disease and mortality among people with diabetes
BACKGROUND When a patient experiences an event other than the one of interest in the study, usually the probability of experiencing the event of interest is altered. By contrast, disease-free survival time analysis by standard methods, such as the Kaplan-Meier method and the standard Cox model, does not distinguish different causes in the presence of competing risks. Alternative approaches use ...
متن کاملModel Selection for the Competing-Risks Model With and Without Masking
The competing risks model is useful in settings in which individuals (or units) may die (or fail) due to a number of different causes. It can also be the case that for some of the items the failure cause is known only up to a subgroup of all causes in which case we say that the failure is group masked. A widely used approach for competing risks data with and without masking involves the specifi...
