Eilers & Peeters Model Modification
Description
This function enhances the Eilers and Peeters (1988) model by adding parameters not originally included in the model, which were introduced by other models. It also renames parameters to a standardized naming convention used across all models.
Usage
eilers_peeters_modified(model_result)
Arguments
model_result |
A list containing the results of the model, including parameters such as |
