A Cox model for component lifetimes with spatial interactions
Résumé
In this paper, we consider n components displayed on a structure (e.g., a steel plates). We define a Cox-type model for the hazard function which includes spatial dependency between components. The state (non-failed or failed) of each component is observed at some inspection times. From this data, we propose to use the SEM algorithm to estimate the parameters of the model. A study based on numerical simulation is then provided.
