How to characterize mathematical models for comparison

Click For Summary

Discussion Overview

The discussion focuses on how to characterize mathematical models for comparison, particularly in the context of wildlife biology. Participants explore various aspects that can be used to evaluate and compare different models, including their applications and the advantages and disadvantages associated with them.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests characterizing models based on aspects such as statistical vs dynamical, linear or nonlinear, and data requirements.
  • Another participant asserts that many models are systems of differential equations, citing examples like Lotka-Volterra and the SIR model, but notes the difficulty in listing all possible models.
  • Some participants emphasize the need for specificity regarding what is being modeled, indicating that the characterization may vary significantly based on the context.
  • A participant recalls a previous discussion about creating a lexicon of differential equations and their applications, highlighting the extensive effort required to provide valuable descriptions.
  • One participant asks for clarification on what specific advantages and disadvantages are relevant to the application in the field of study.

Areas of Agreement / Disagreement

Participants generally agree on the complexity and variety of mathematical models but do not reach a consensus on specific aspects for characterization or the importance of particular advantages and disadvantages.

Contextual Notes

The discussion lacks specificity regarding the type of models being compared, which may influence the characterization process. There are also unresolved questions about the essential aspects that should be prioritized in the comparison.

TL;DR
identifying components of a model
I am reviewing and comparing a wide range of mathematical models that are being applied to a specific realm of wildlife biology. For the comparison of these models, and to weigh advantages/disadvantages of different aspects with regard to application, I need to characterize each model. As I do not yet have a great amount of experience working with models I am unsure of essential model aspects that can be used to characterize them. Examples that I have thought of are statistical vs dynamical, linear or nonlinear, heavy or low data requirement...
Can you provide a list of aspects you would use to characterize a model, to be used for comparison?

Any model is probably a system of differential equations. To list them is basically impossible as there are so many. Famous examples are Lotka-Volterra for predator prey models, or the SIR model for epidemics.
 
There are a great many aspects to model and you have not specified what is being modeled. You might start with this article and the links in it and go from there to the specific type of model that you are interested in.

I remember a thread in which someone asked about a list of differential equations vs. applications, like a lexicon. I started and searched a few on the internet only to find out, that - if added valuable descriptions of both, model and application - this would turn into a job of decades! But it would certainly be of value.

Specifically, what "advantages/disadvantages" are important "with regard to application" in your field of study?
