BayesFusion has released Metalog Builder, an interactive tool for constructing metalog distributions, accessible to the decision modeling community through a web interface at https://metalog.bayesfusion.com/. Metalog distribution (also known as the Keelin distribution) is extremely flexible and is capable of fitting many naturally occurring distributions. It can be specified by probability quantiles and it is able to represent distributions that are unbounded, semi-bounded, and bounded. The Metalog Builder page mimics the functionality of the Metalog Builder window in GeNIe, which in turn is inspired by the elicitation tools built by Tom Keelin and colleagues. For more information about the interface, please refer to the GeNIe Modeler manual page for the Metalog Builder.
