spatialRF (version 1.1.5)

get_residuals: Extract model residuals

Description

Extracts residuals (observed - predicted values) from models fitted with rf(), rf_repeat(), or rf_spatial().

Usage

get_residuals(model)

Value

Numeric vector of residuals with length equal to the number of training observations. For rf_repeat() models, returns the median residual across repetitions.

Arguments

model

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

Details

Residuals are calculated as observed minus predicted values. They can be used to assess model fit, check assumptions, and diagnose patterns such as spatial autocorrelation (see get_moran()). Ideally, residuals should be randomly distributed with no systematic patterns.

# Extract residuals
residuals <- get_residuals(plants_rf)
head(residuals)

# Check basic statistics
summary(residuals)

# Plot distribution to check for patterns
