residuals.spconform

Calculates prediction residuals (observed minus fitted values) or
nonconformity scores for an <code>spconform</code> object given true responses.

Provides distribution-free, model-agnostic prediction
intervals for spatially and spatio-temporally dependent data using
localized conformal calibration. Implements locally weighted split
conformal prediction for geostatistical (point-referenced) data based on
spatial-distance kernels, and a neighbourhood-weighted conformal
procedure for areal (lattice) data based on graph adjacency structures.
Relaxes the standard exchangeability assumption using spatial proximity,
following the localized conformal framework of Mao, Martin and Reich
(2024) <doi:10.1080/01621459.2022.2147531>. Includes comprehensive
spatial diagnostic tools to audit empirical coverage, conditional
spatial strata, and boundary proximity effects.
