How to Estimate Accuracy of Different Models: Non-Gaussian Case

摘要

In geophysics, we usually have several Earth models based on different types of data: seismic, gravity, etc. Each of these models captures some aspects of the Earth structure. To properly combine these models, it is important to know the accuracy of different models. In our previous papers, we showed how this accuracy can be estimated under the assumption that the inaccuracy of these models is normally distributed. In practice, however, the distribution of the model inaccuracy is often non-Gaussian. In this paper, we describe how accuracy estimation methods can be extended to the non-Gaussian case.
