Keelin Multivariate Metalogs and Golf 17 May 2023

Описание: "The Multivariate Metalog Distributions: An Introduction with Application to Strategic Decision-Making in Golf" is a webinar jointly sponsored by the Society of Decision Professionals and the Decision Analysis Society on May 17, 2023. This is the uninterrupted (54 min) recording. An associated preprint article is available for download: https://osf.io/cdmrv.

It introduces the multivariate metalog distributions and applies them to a decision analysis of strategic decision-making in golf. Like the univariate metalog distributions, the multivariate metalog distributions are shape- and bounds-flexible, have simple closed-form quantile functions, and are easy to parameterize, fit to data, interpret, and simulate.

Two methods for constructing continuous multivariate probability distributions using metalogs are described. The first employs unconditional and conditional quantile parameters that can be visualized as a probability tree. The second employs copulas with metalog marginal distributions.

Both methods are illustrated with an easy-to-understand practical application: in golf, choosing the best aimpoint can make the difference between winning and losing.
