NONLINEAR MODEL Meaning and
Definition
-
A nonlinear model is a mathematical or statistical model that does not follow a linear relationship between the variables. In contrast to linear models, nonlinear models exhibit more complex patterns and are characterized by curved or irregular relationships among variables.
Nonlinear models are commonly used in various fields, particularly in physics, economics, engineering, and social sciences, where relationships between variables are not expected to be linear. These models can capture intricate phenomena, such as exponential growth, decay, saturation, oscillations, or interactions among variables.
In a nonlinear model, the relationship between the dependent variable(s) and the independent variable(s) is represented by a nonlinear equation or a system of nonlinear equations. This could involve polynomial functions, exponential functions, logarithmic functions, trigonometric functions, or any other non-linear function.
Due to the complexity and non-linearity of these models, they often require advanced techniques for estimation, inference, and prediction. Nonlinear regression analysis, for example, is a statistical method used to estimate the parameters of a nonlinear model. Other approaches to nonlinear modeling include neural networks, support vector machines, decision trees, and evolutionary algorithms.
Nonlinear models are valuable tools for explaining and predicting real-world phenomena that involve intricate relationships between variables. By capturing the nonlinear nature of these relationships, these models provide a more accurate representation of the underlying dynamics and enable researchers to gain deeper insights into complex systems.

Etymology of NONLINEAR MODEL
The word "nonlinear" is formed by combining the prefix "non-" meaning "not" or "without" with the word "linear".
The term "linear" comes from the Latin word "linearis", which means "belonging to lines". It ultimately traces back to the Latin noun "linea", which means "line". In mathematics, a linear relationship between variables refers to a straight-line relationship, where the change in one variable is directly proportional to the change in another variable.
On the other hand, "model" comes from the Latin word "modulus", which means "measure" or "standard". It entered the English language from the Old French word "modelle".
