On the testing of seismicity models [PDF]
Acta Geophysica, 2011 Recently a likelihood-based methodology has been developed by the Collaboratory for the Study of Earthquake Predictability (CSEP) with a view to testing and ranking seismicity models. We analyze this approach from the standpoint of possible applications to hazard analysis.

Test Cost-Test Quality Modeling For Adaptive Test
2022 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2022 The ever increasing complexity of chips continuously challenges the goal of delivering a target test quality at a feasible cost. Adaptive testing has emerged as a method to explore test quality and test cost tradeoff. The modeling of the relation between test quality and test cost can enable the identification of optimal test cost and test quality ...
