TL;DR: Two new metrics of approximation are proposed: the Kullback-Leibler discrepancy of spectral densities and the chi-squared distance between spectral densITIES, which are minimized to obtain the approximations of GGMs and GMRFs. (via Semantic Scholar)

TL;DR: A multivariate spatial regression model is developed for the estimation of the risk of mortality associated with fine PM and its components across all counties in the conterminous United States and shows that in the Western United States, the nitrate and crustal components of the speciated fine PM seem to have more impact on mortality than the other components.
