AI Overview: Polynomial regression is a form of regression analysis in which the relationship between the independent variable and the dependent variable is modeled as an nth degree polynomial. It extends linear regression by introducing polynomial terms to capture more complex relationships in data. Polynomials consist of variables and coefficients combined using addition, subtraction, and multiplication, allowing for diverse modeling capabilities that can fit curves to data more effectively than linear models. This technique is advantageous for capturing nonlinear trends in data.
Polynomial
In mathematics, a polynomial is a mathematical expression that is a sum of multiple terms called monomials, including numbers, variables, or products of numbers and variables. Polynomials use only addition, subtraction, multiplication, and whole number exponentiation. They are fundamental in algebra, often forming polynomial equations and functions. Terms in a polynomial can be categorized by their number, degree, and other properties, such as monomials (one term), binomials (two terms), and trinomials (three terms). Key terms include coefficients, variables, constants, and varying degrees from linear to quintic and sextic.

This page redirects to the Polynomial topic, which encompasses the study of mathematical expressions consisting of variables and coefficients, combined using addition, subtraction, multiplication, and non-negative integer exponents.
Local Regression
Local regression, or local polynomial regression, is a smoothing technique used for scatterplots, encompassing methods known as LOESS (locally estimated scatterplot smoothing) and LOWESS (locally weighted scatterplot smoothing). These non-parametric techniques are also referred to as the Savitzky–Golay filter in some fields.

Regression Analysis
Regression analysis is a statistical tool used to show the relationship between inputs and outputs in a system, commonly employed for trend prediction and causal studies. The foundational technique is linear regression, with the method of least squares introduced by A.M. Legendre in 1805 and further developed by C.F. Gauss in 1809, both of whom applied it to celestial mechanics.
Monomial
In mathematics, a monomial is a polynomial with only one term and it cannot have a variable in the denominator.
Linear Regression
Linear regression is a statistical method used to understand the relationship between a dependent variable and one or more explanatory variables by fitting a straight line to observed data points. It minimizes the vertical distances (residuals) between the line and the points, commonly using the least squares method. Linear regression is widely used in various fields, especially economics, for predictive modeling and quantifying relationships among variables.
Regression in Psychology
Regression is a defense mechanism in psychology where the ego reverts to an earlier state to avoid confronting impulses maturely. A common manifestation of regression includes adopting the fetal position during times of stress, illness, or injury.
Quartic Equation
A quartic equation is a polynomial of the fourth degree in algebra, expressed in a specific mathematical form.
Curve Fitting
Curve fitting is the process of constructing a mathematical function that best fits a set of data points. It can involve interpolation (exact fit to data) or smoothing (approximate fit). This technique aids in data visualization, estimating function values in data gaps, and summarizing relationships between variables. Extrapolation extends the curve beyond observed data, but carries uncertainty depending on the curve construction method.
