Nonlinear Model
Definition
A nonlinear model is a statistical model that does not follow a straight line relationship between the independent and dependent variables. It involves curves, exponential functions, or other non-linear patterns.
Analogy
Think of a roller coaster ride where the speed of the ride doesn't increase or decrease at a constant rate. Instead, it goes up and down in unpredictable ways, creating twists and turns that are not linear.
Related terms
Exponential Growth: A type of nonlinear model where the dependent variable increases at an accelerating rate over time.
Quadratic Equation: A specific type of nonlinear model that follows a U-shaped curve.
Logarithmic Function: Another example of a nonlinear model where the dependent variable increases but at a decreasing rate as the independent variable increases.
