Abstract : This report presents results on a theoretical formulation and algorithms for reconstructing Granger causality graphs (GCG) from collections of wide sense stationary (WSS) and cyclostationary time series data. The thrust of the research was to develop methods for GCG sparsification using ideas from Tikhonov regularization and ADMM based proximal algorithms. Several computational examples are presented.
