In risk analysis, researchers often fit many candidate distributions to frequency and severity data and select based on goodness-of-fit. In a new study published in Risk Sciences, the authors ...

The team developed a non-parametric, model-free approach to quantify memory in complex systems such as soil, oceans, and ...
