Claim 0:
1. A method for characterizing susceptibility of an inferential model to follow signal degradation, comprising:
receiving a set of time-series signals associated with sensors in a monitored system during normal fault-free operation;
training the inferential model using the set of time-series signals; and
characterizing susceptibility of the inferential model to follow signal degradation by,
adding degradation to a signal in the set of time-series signals to produce a degraded signal,
using the inferential model to perform prognostic-surveillance operations on the set of time-series signals with the degraded signal, and
characterizing the susceptibility of the inferential model to follow degradation in the signal based on results of the prognostic-surveillance operations.
