PolynomialRegressionModel Class

Represents a polynomial regression model.

Definition

Namespace: Numerics.NET.Statistics
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
C#
public class PolynomialRegressionModel : LinearRegressionModel
Inheritance
Object  →  Model  →  RegressionModel<Double>  →  LinearRegressionModel  →  PolynomialRegressionModel

Remarks

Use the PolynomialRegressionModel class to represent a linear regression model that uses polynomials in one variable.

PolynomialRegressionModel inherits from LinearRegressionModel, but has special constructors that make it easier to create polynomial regression models in one variable. It also defines some members that may be more appropriate for the simple case. For example, the GetRegressionPolynomial() method returns a Polynomial object that represents the resulting regression curve.

Constructors

PolynomialRegressionModel(Vector<Double>, Vector<Double>, Int32) Constructs a new PolynomialRegressionModel.
PolynomialRegressionModel(IDataFrame, String, String, Int32) Constructs a new PolynomialRegressionModel.
