Understanding competing risks: a simulation point of view

BACKGROUND Competing risks methodology allows for an event-specific analysis of the single components of composite time-to-event endpoints. A key feature of competing risks is that there are as many hazards as there are competing risks. This is not always well accounted for in the applied literature. METHODS We advocate a simulation point of view for understanding competing risks. The hazards...

Parametric 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. ...

Competing risks.

Consider a unit which can experience any one of k competing failure types, and suppose that for each unit we observe the time to failure, T , and the type of failure, C ∈ {1, 2, . . . , k}. The case of observing the pair (T, C) is termed “competing risks” in the statistical literature. After considering some examples we review basic notation and theory of competing risks. In particular we consi...

Understanding Urban Growth Patterns: a Landscape Ecology Point of View

Landscapes always change, as they are the expression of the constant interaction between natural and cultural forces in the environment. Applied to an urban/peri-urban case, changes are seen as a menace. By identifying the past urbanization patterns, policy makers and planners can gain better insight into the contributing factors that have resulted in the most problematic development patterns n...

Understanding Dependent Competing Risks: A Simulation Study to Illustrate the Relationship Between Cause-Specific Hazard and Marginal Hazard

In the analysis of competing risk data, the observed effect of a covariate can be obtained via a Fine and Gray sub-distribution hazard ratio. Sometimes, it is also desirable to obtain the virtual effect of a covariate as if the competing risks were non-existent. Under the latent failure time scenario, when the event of interest and the competing risk event are independent, the cause-specific ha...
