WebApr 23, 2016 · In this paper, we consider the problem of fitting a sparse precision matrix to multivariate Gaussian data. The zero elements in the precision matrix correspond to conditional independencies between variables. We focus on the estimation of a class of sparse precision matrix which represents the scale-free networks. It has been … WebA set of tools for representing and estimating sparse Bayesian networks from continuous and discrete data. Overview. This package provides various S3 classes for making it easy to estimate graphical models from data: sparsebnData for managing experimental data with interventions. sparsebnFit for representing the output of a DAG learning algorithm.
