Plot Model Performance

Visualizes model performance metrics produced by compare_models().

Usage

plot_model_performance(comparison)

Arguments

comparison

Output from compare_models().

Value

A ggplot2 object.

Details

This plot provides a graphical comparison of competing models using goodness-of-fit statistics.

Typical metrics include:

• R-squared (R²)

• Root Mean Squared Error (RMSE)

• Residual Sum of Squares (RSS)

• Akaike Information Criterion (AIC)

• Bayesian Information Criterion (BIC)

The visualization helps identify models that balance goodness of fit and model complexity.
