LikelihoodGeometry: Macaulay2 Package

This note introduces the $\mathtt{\text{LikelihoodGeometry}}$ package for the computer algebra system $\mathit{\text{Macaulay2}}$. This package gives tools to construct the likelihood correspondence of a discrete algebraic statistical model, a variety that that ties together data and their maximum likelihood estimators. This includes methods for constructing and combining popular statistical models and calculating their ML-degree.
