GlobalGrowthComparison {biogrowth}R Documentation

GlobalGrowthComparison class


The GlobalGrowthComparison class contains several functions for model comparison and model selection of growth models. It should not be instanced directly. Instead, it should be constructed using compare_growth_fits(). It is similar to GrowthComparison, although with specific tools to deal with several experiments.

It includes two type of tools for model selection and comparison: statistical indexes and visual analyses. Please check the sections below for details.

Note that all these tools use the names defined in compare_growth_fits(), so we recommend passing a named list to that function.

if type==1, the plot compares the model predictions. If type ==2, the plot compares the parameter estimates. If type==3, the plot shows the residuals


should a trend line of the residuals be added for type==3? TRUE by default

Methods (by generic)

Statistical indexes

GlobalGrowthComparison implements two S3 methods to obtain numerical values to facilitate model comparison and selection.

Visual analyses

The S3 plot method can generate three types of plots:

These plots are divided by facets for each experiment.
