1. A computer-implemented method for determining a corrective action, comprising: obtaining diagnostic data; calculating, using the diagnostic data, a prognostic; retrieving, when the prognostic is above an alarm level, historical records; calculating a Bayesian posterior probability using the diagnostic data and the historical records; calculating a prognostic prescience metric using the diagnostic data and the historical records; and determining, based on the Bayesian posterior probability and the prognostic prescience metric, the corrective action.
