How to characterize mathematical models for comparison

AI Thread Summary
The discussion revolves around the need to characterize various mathematical models used in wildlife biology for effective comparison. Key aspects for characterization include the model type (statistical vs. dynamical), data requirements, and whether they are linear or nonlinear. The complexity of creating a comprehensive list of differential equations and their applications is acknowledged, emphasizing the challenge of providing valuable descriptions. Participants highlight the importance of specifying the particular models and their applications to better understand their advantages and disadvantages. Ultimately, a focused approach on specific model characteristics relevant to wildlife biology is necessary for meaningful comparisons.

TL;DR Summary
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?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
