and complex-valued graphical lasso (CGLASSO) via a pathwise
coordinate descent algorithm for complex-valued parameters,
using an isomorphism between complex numbers and 2x2 orthogonal
matrices. Also provides a full inference pipeline for
high-dimensional sparse spectral precision matrices, including
data-driven bandwidth selection, one-step debiasing, asymptotic
variance estimation, entry-wise confidence regions, and
FDR-controlled hypothesis testing. Supporting tools for
cross-validation, simulation, coefficient extraction, and
plotting are included. See Deb, Kuceyeski, and Basu (2024)
