Closure Properties and Diagnostic Plots for the Frailty Distribution in Proportional Hazards Modelsed frailty, where the members of a cluster share a common value of frailty. A similar plot can be used when the cluster lifetime is defined as the shortest lifetime of the cluster’s members. Other definitions of cluster lifetime are less useful for this purpose because the closure property does not apply.

A Competing Risks Model for Degradation and Traumatic Failure Timesed. Very often, longitudinal observations of degradation values (measured with error) are available for each item until the first failure. We are mainly interested here in the nonparametric estimation of the cumulative intensity function of the traumatic failure time and related reliability characteristics.

Sampling in Survival Analysis and Estimation with Unknown Selection Bias and Censoringnsored, as soon as the individual is selected, we construct a product-limit estimator .. for the d.f. .. and a nonparametric estimator . for the weighting function .. We investigate the behavior of these estimators through a simulation study.

Virtual (Biological) Age Versus Chronological Age the chronological age in a baseline environment. The second approach is based on considering an observed level of individual degradation and on its comparison with some average, “population degradation.” The virtual age of the series system is also defined via the corresponding weighting of individual virtual ages.

Nested Plans for Sequential Change Point Detection—The Parametric Casetrol (time to change detection) cases. We assume that the initial and the final distributions come from an exponential family of distributions and show the existence of optimal nested plans in the one-parameter case and for the multivariate normal case.
