Multi-level hypotheses testing provides a more precise characterization of emerging faults than the bi-level fail/no-fail hypothesis, and is often essential for early warning and timely detection and identification of soft failures in degrading devices. This paper formulates recursive relations for testing multi-level hypotheses for real-time detection and identification of emerging faults from uncertain continuous sensor signals
