spatialRF (version 1.1.5)

get_evaluation: Extract evaluation metrics from cross-validated model

Description

Extracts aggregated performance metrics from a model evaluated with rf_evaluate().

Usage

get_evaluation(model)

Value

Data frame with aggregated evaluation metrics containing:

• model: Model type - "Full" (original model), "Training" (trained on training folds), or "Testing" (performance on testing folds, representing generalization ability).

• metric: Metric name - "rmse", "nrmse", "r.squared", or "pseudo.r.squared".

• mean, sd, min, max: Summary statistics across cross-validation repetitions.

Arguments

model

Model object with class rf_evaluate from rf_evaluate().

Details

This function returns aggregated statistics across all cross-validation repetitions. The "Testing" model metrics indicate the model's ability to generalize to unseen spatial locations.
