plot_model_comparison_treatment: Compare Models for a Treatment

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

Compare Models for a Treatment

Description

Displays observed and predicted gas production values for multiple fitted models across all replicates of a selected treatment.

Usage

plot_model_comparison_treatment(..., treatment)

Arguments

...	Fitted model objects.
treatment	Treatment name.

Details

Observed measurements are displayed alongside model predictions, allowing visual comparison of competing kinetic models within a treatment.

This visualization is useful for:

• Comparing competing models

• Evaluating model performance by treatment

• Assessing agreement among biological replicates

• Identifying systematic prediction errors

Value

A ggplot2 object.
