Coarse-to-Fine Spatial and Spatio-Temporal Modeling // Provides functions for coarse-to-fine spatial and spatio-temporal modeling, enabling fast prediction, regression, and uncertainty quantification for moderate to large datasets. For methodological details, see Murakami et al. (2026) doi:10.1111/gean.70034 and related work on generalized linear, downscaling, and dynamic spatio-temporal extensions.
