LSVAR: Estimation of Low Rank Plus Sparse Structured Vector Auto-Regressive (VAR) Model
Implementations of estimation algorithm of low rank plus sparse structured VAR model by using Fast Iterative Shrinkage-Thresholding Algorithm (FISTA). It relates to the algorithm in Sumanta, Li, and Michailidis (2019) <doi:10.1109/TSP.2018.2887401>.
