NonlinearRegressionModel Class

Represents a nonlinear regression model.

Definition

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

Remarks

Use the NonlinearRegressionModel class to analyze a nonlinear relationship between two or more numerical variables. A nonlinear regression model tries to express one variable, called the dependent variable, as a function of one or more other variables called independent variables or predictors.

The nonlinear model is specified in the form of a NonlinearCurve.
