Compare interpolation methods

Compare multiple interpolation methods using cross-validation and return performance metrics for method selection.

Usage

compare_interpolation_methods(
  spatial_data,
  target_variable,
  methods = c("NN", "simple", "spline"),
  cv_folds = 5,
  verbose = TRUE
)

Arguments

spatial_data

Spatial data for interpolation

target_variable

Variable to interpolate

methods

Vector of methods to compare

cv_folds

Number of cross-validation folds

verbose

Print comparison results

Value

Data frame with method comparison results

Examples

if (FALSE) { # \dontrun{
# These examples require external data files not included with the package
# Compare interpolation methods
method_comparison <- compare_interpolation_methods(
  soil_data,
  target_variable = "nitrogen",
  methods = c("NN", "simple", "spline"),
  cv_folds = 10
)

# View results
print(method_comparison)
# Best method
best_method <- method_comparison$method[which.min(method_comparison$rmse)]
} # }
