Epistemic Uncertainties: Dealing with a Lack of Knowledge

  • Ryan G. McClarren


This chapter attempts to assess the impact of uncertainties that do not have a known distribution. In Sect. 12.1 we introduce a metric for evaluating the agreement between simulation and experiments. We then extend our focus to the case of agreement between experiment and simulation when there are calibration parameters in the simulation. We treat these cases using horsetail plots and p-boxes. To make a prediction on a new experiment, we can use the p-box to adjust a prediction, as shown in Sect. 12.4. Section 12.5 introduces Dempster-Shafer evidence theory for including expert judgment to construct p-boxes, followed by Sect. 12.6 where Kolomogorov-Smirnov confidence bounds are presented and Sect. 12.7 on Cauchy deviates.
