Adventures in Reliability: Heavily Censored Data
Abstract
At times reliability data are recorded as exact failure times on systems. This is a trivial case that is handled usually by simple textbook analysis approaches. Many times, especially in the T&E community, all that is known regarding failures is that a certain number of events have been observed during a flight. These type of data are called 'interval data' and do not equate with exact failure times. Trivial analysis approaches can severely bias MTBF estimates and 'paint a pretty picture.' In this presentation statistical techniques for handling this data are discussed.
