Abstract
Let T be time-to-event (failure time), which is a nonnegative random variable. In medicine, a typical example is time from the onset of a condition or an initiation of treatment to death. In studies of reliability of products (or components), time to failure of light bulbs, for example, is often of interest. Rather than using such specific terms, economists refer to durations between events (e.g., duration of unemployment). The distribution of failure time is usually non-normal and skewed.
