Constant difference model (a.ka Linear) 2.1 Introduction TODO: Introduce the constant difference model. Explain the assumptions and put a nice-looking mathematical formula for it. 2.2 Questions 1. What assumptions does this model make? The amount of change is the same every year 2. What is it also known as a liner odel? 3. How does the model's long-term behavior depend on the value of the parameter b? Constant difference model (a.ka Linear) 2.1 Introduction TODO: Introduce the constant difference model.
