Description: Implements the Singularity Regression Kriging ('SRK')
        model for spatial prediction by integrating covariate
        singularity feature construction, nonlinear trend estimation
        via random forest, and geostatistical interpolation of
        residuals using ordinary kriging. Singularity-based anomaly
        indices are computed from environmental covariates at multiple
        spatial scales to capture local multiscale heterogeneity and
        augment the random forest feature set for trend estimation. The
        resulting residuals are interpolated using ordinary kriging to
        generate final spatial predictions with uncertainty
        quantification. Tools for spatial block cross-validation,
        parameter sensitivity analysis, and diagnostic visualization
        are also provided. Methods are based on Ren, Song, Chen, and Yu
        (2026) <doi:10.1080/15481603.2026.2690341>, with singularity
        theory from Cheng (2012) <doi:10.1016/j.gexplo.2012.07.007> and
        Cheng (2017) <doi:10.1016/j.gr.2017.07.011>, random forest
        methodology from Breiman (2001) <doi:10.1023/A:1010933404324>,
        and regression kriging framework from Hengl, Heuvelink, and
        Rossiter (2007) <doi:10.1016/j.cageo.2007.05.001>.
