Title: Nonparametic System reliability estimation via shrinkage

Abstract: In a coherent reliability system composed of multiple components configured according to a specific structure function, the distribution of system time to failure, or system lifetime, is often of primary interest. The system lifetime distribution can be estimated directly using the observed system failure times. However, when component-level lifetime data is available, it can yield improved estimates of system reliability. In this talk, I’d like to discuss that under nonparametric assumptions about the component time-to-failure distributions, traditional estimators such as the product-limit estimator can be further improved under specific loss functions. A novel methodology is developed in this setting through a shrinkage transformation applied to component-level estimators.
