spatialRF (version 1.1.5)

get_moran: Extract Moran's I test results for model residuals

Description

Extracts Moran's I test results for spatial autocorrelation in model residuals from models fitted with rf(), rf_repeat(), or rf_spatial().

Usage

get_moran(model)

Value

Data frame with Moran's I statistics at multiple distance thresholds. Columns include distance.threshold, moran.i (statistic), p.value, interpretation, and method.

Arguments

model

Model object from rf(), rf_repeat(), or rf_spatial().

Details

Moran's I tests for spatial autocorrelation in model residuals. Significant positive values indicate residuals are spatially clustered, suggesting the model hasn't fully captured spatial patterns. For spatial models (rf_spatial()), low or non-significant Moran's I values indicate successful removal of spatial autocorrelation.
