bigmatrix (0.9.6)

Tuning Insensitive Graph Estimation and Regression.

The package "bigmatrix" estimates high dimensional precision matrices for Gaussian graphical models. We adopt three estimation procedures based on column by column regression: (1) Tuning-Insensitive Graph Estimation and Regression (TIGER); (2) The Constrained L1 Minimization for Sparse Precision Matrix Estimation (CLIME); (3) Adaptive CLIME for Sparse Precision Matrix Estimation (ADP). The optimization algorithms for all three methods are based on alternative direction method combined with coordinate decent. The computation is memory-optimized using the sparse matrix output.
