We analyze data sampled from a population of parts in which an associated anomaly can occur at assembly or after assembly. Using a zero‐inflated lifetime distribution to fit left‐censored and right‐censored data as well data from a supplementary sample, we make predictions about the proportion of the population with anomalies today and in the future. Goodness‐of‐fit is also addressed. Copyright © 2016 John Wiley & Sons, Ltd.
