WebThis rate is commonly referred as the hazard rate. Predictor variables (or factors) are usually termed covariates in the survival-analysis literature. The Cox model is expressed by the hazard function denoted by h(t). Briefly, … WebIf sufficient historical failure life data exist, the failure distribution of the system can be estimated to identify the system initial hazard function.
