spatialkit: Spatial Tessellation, Modeling, and Cross-Validation Toolkit
Constructs analysis regions from the distribution of the data
itself, as an alternative to aggregating onto administrative boundaries
that were drawn for unrelated purposes. Seeds and builds Voronoi,
Delaunay, hexagonal and square tessellations with reproducible
identifiers, selects a cell count from the spatial structure of the
observations, assigns features to cells, and aggregates to cell level
with optional design-effect corrections so that standard errors account
for within-cell autocorrelation. Also manages coordinate reference
systems. Fits geographically weighted regression
(via 'GWmodel'; Lu et al. (2014) <doi:10.1080/10095020.2014.917453>),
Bayesian spatial Gaussian process regression (via 'brms', using the
Hilbert space approximation of Riutort-Mayol et al. (2023)
<doi:10.1007/s11222-022-10167-2>) and random forests (via 'ranger', with
the permutation importance of Strobl et al. (2007)
<doi:10.1186/1471-2105-8-25>), each behind one S3 class with consistent
predict, fitted, residuals and plot methods. Provides spatial
cross-validation with random, block, buffered, leave-location-out and
nearest-neighbour distance-matched folds (Mila et al. (2022)
<doi:10.1111/2041-210X.13851>), forward variable selection, model
comparison, prediction onto a regular surface, and the area of
applicability of Meyer and Pebesma (2021) <doi:10.1111/2041-210X.13650>
to flag where a fitted model extrapolates beyond its training data.
