POLYNOMIAL MODEL Meaning and
Definition
-
A polynomial model, in mathematics and statistics, refers to a mathematical representation used to describe and approximate the relationship between a dependent variable and one or more independent variables. It is a type of regression model that is comprised of polynomial functions.
In a polynomial model, the dependent variable is expressed as a polynomial of specified degree in terms of the independent variables. The degree refers to the highest power of the independent variable(s) within the polynomial. The model assumes that the relationship between the variables can be explained by a polynomial equation.
The polynomial model is a versatile tool that can capture a wide range of non-linear relationships between variables. By including higher order terms, such as squared or cubed variables, the model can account for curvature and more complex patterns in the data. This allows for a better fitting of the data compared to simpler linear models.
Polynomial models are often used in fields such as physics, engineering, economics, and social sciences. They offer a flexible and systematic approach to modeling relationships between variables, enabling predictions and analysis of complex systems.
It is important to note that the choice of degree in a polynomial model should be carefully considered. An excessively high degree may lead to overfitting, where the model fits the training data extremely well but fails to generalize to new data. Therefore, model selection techniques, such as cross-validation, should be employed to determine the optimal degree for the polynomial model.

Etymology of POLYNOMIAL MODEL
The word "polynomial" has its roots in Greek. It comes from the combination of two words, "poly", meaning "many", and "nomial", which is derived from the Greek word "nomos", meaning "law" or "rule". Therefore, "polynomial" can be understood as "many terms" or "many expressions".
The term "model" has its origins in the Latin word "modulus", which means "measure" or "standard". It entered the English language through Old French and has various meanings related to representation, structure, or idealized versions.
When combined, "polynomial model" refers to a mathematical representation or function that comprises multiple terms or expressions, according to a standard or rule. In statistics and data analysis, polynomial models are used to describe relationships between variables, allowing for more complex and flexible modeling compared to simple linear regression.
