In rumenGP: Rumen Gas Production Modeling, Comparison, and Visualization

Plot Model Rankings

Description

Visualizes model rankings across multiple performance metrics.

Usage

plot_model_rankings(ranking)

Arguments

ranking

Output from rank_models().

Details

Rankings are typically based on metrics such as:

• R-squared (R²)

• Root Mean Squared Error (RMSE)

• Residual Sum of Squares (RSS)

• Akaike Information Criterion (AIC)

• Bayesian Information Criterion (BIC)

This visualization helps identify models that consistently perform well across several evaluation criteria.

Value

A ggplot2 object.
