Dynamic Chain Graph Models for Ordinal Time Series Data
Pariya Behrouzi, Fentaw Abegaz, Ernst C. Wit
This paper introduces sparse dynamic chain graph models for network inference in high dimensional non-Gaussian time series data. The proposed method parametrized by a precision mat…

Penalized EM algorithm and copula skeptic graphical models for inferring networks for mixed variables
Fentaw Abegaz, Ernst Wit
In this article, we consider the problem of reconstructing networks for continuous, binary, count and discrete ordinal variables by estimating sparse precision matrix in Gaussian c…
