Sentences with phrase «nonlinear models»
Nonlinear models refer to mathematical models that do not follow a straight line or a predictable pattern. Instead, they describe more complex relationships between variables where changes in one variable do not produce proportional changes in another. These models are useful for understanding and predicting real-world phenomena with curved or irregular behavior. Full definition
