Carlos Améndola, Luis David García Puente, Roser Homs, Olga Kuznetsova, Harshit J. Motwani

摘要:

我们介绍的软件包“GraphicalModelsMLE”计算的最大似然估计(MLEs)的高斯图形模型的计算机代数系统Macaulay 2。该软件包允许计算无环混合图类的最大似然估计。额外的功能允许用户探索模型的基本代数结构,例如其极大似然度和分数方程的理想。

英文摘要:

We introduce the package "GraphicalModelsMLE" for computing the maximum likelihood estimates (MLEs) of a Gaussian graphical model in the computer algebra system Macaulay2. This package allows the computation of MLEs for the class of loopless mixed graphs. Additional functionality allows the user to explore the underlying algebraic structure of the model, such as its maximum likelihood degree and the ideal of score equations.
