Maximum Likelihood Estimation for Totally Positive Log-Concave Densities
Elina Robeva, Bernd Sturmfels, Ngoc Tran +1
We study nonparametric maximum likelihood estimation for two classes of multivariate distributions that imply strong forms of positive dependence; namely log-supermodular (MTP)…
High-Dimensional Joint Estimation of Multiple Directed Gaussian Graphical Models
Yuhao Wang, Santiago Segarra, Caroline Uhler
We consider the problem of jointly estimating multiple related directed acyclic graph (DAG) models based on high-dimensional data from each graph. This problem is motivated by the…
Geometry of Discrete Copulas
Elisa Perrone, Liam Solus, Caroline Uhler
Multivariate distributions are fundamental to modeling. Discrete copulas can be used to construct diverse multivariate joint distributions over random variables from estimated univ…
