What are models?
- Physical systems represented in math form
- A commitment of certain understanding
- Approximation of parts of reality
- Abstractions
- Mathematical equations
- Can be a computer program
- Characterized by
- Variables (the things that change)
- Parameters (the things that don’t change)
- Functional forms (the relationship that connects the two)
How you model a system is completely dependent on why you want to model the system. If you want to make predictions about something, you need to include that something in the model in the first place.
