The basic idea is to merge exploration with confirmation \insertCite@see for example, @rodriguez_williams_rast_mulder_2020GGMncv. This is accomplished by testing those edges (in an independent dataset) that were initially detected via data driven model selection.
Confirmatory hypothesis testing follows the approach described in \insertCitejankova2015confidence;textualGGMncv: (1) graphical lasso is computed with lambda fixed to \mjseqn\lambda = \sqrtlog(p)/n, (2) the de-sparsified estimator is computed, and then (3) p-values are obtained for the de-sparsified estimator.
