High-dimensional Gaussian Graphical Model Testing for Long-Memory Time Series

arXiv:2609.30565v1 Announce Type: cross Abstract: Many real-world high-dimensional time series exhibit long-memory, but Gaussian graphical model testing in this regime remains understudied. We develop a direct, data-adaptive test statistic for assessing conditional independence in the graph structu…
