Prognostic performance evaluation is of key importance for a successful PHM system deployment. The early lack of standardized methods for performance evaluation and benchmark data-sets resulted in reliance on conventional performance metrics borrowed from statistics. Those metrics were primarily accuracy and precision based where performance is evaluated against end of life, typically known a priori in an offline setting. More recently, efforts towards m… http://papers.phmsociety.org/index.php/phme/article/view/1373
