Nonlinear Models

Nonlinear models are mathematical tools used to describe relationships between variables that do not follow a straight-line pattern. Unlike linear models, where changes in one variable produce proportional changes in another, nonlinear models capture more complex, curved, or tangled relationships. These models are useful when data shows increasing, decreasing, or changing rates of effect, such as in biology, economics, or engineering. They help accurately predict and understand systems where simple straight-line assumptions don't apply, enabling more precise analysis of real-world phenomena with intricate dependencies.
