Singularity-based anomaly\nindices are computed from environmental covariates at multiple\nspatial scales to capture local multiscale heterogeneity and\naugment the random forest feature set for trend estimation. The\nresulting residuals are interpolated using ordinary kriging to\ngenerate final spatial predictions with uncertainty\nquantification. Tools for spatial block cross-validation,\nparameter sensitivity analysis, and diagnostic visualization\nare also provided.
