Curve Fitter Class
Definition
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
public abstract class CurveFitter
- Inheritance
- Object → CurveFitter
- Derived
Remarks
Use the CurveFitter class to refer to classes that implement curve fitting algorithms. This is an abstract class and cannot be instantiated. Instead, use one of the derived classes: LinearCurveFitter and NonlinearCurveFitter.
The curve is specified by the Curve property. The data is supplied as Vector objects through the XValues and YValues properties.
The Fit() method performs the actual curve fit. This method returns the Curve that best fits the supplied data.
By default, the observations are unweighted. You can supply a weighting method in two ways. You can set the WeightFunction property to a function of two variables delegate that computes the weight for each observation. The WeightFunctions class provides predefined delegates for the most common weight functions. Alternatively, you can set the individual weights by setting the WeightVector property to a Vector that contains the weight for each individual observation.
