Abstract: In a method for estimating the residual life of machinery statistically by calculating conditional expectations, it is disclosed that different statistical approaches are required for defining the behavior of failure processes related to repairable and non-repairable systems and that diagnostic information should be combined with event information to significantly improve the accuracy of predictions.
