Namespace:  CenterSpace.NMath.Analysis
Assembly:  NMath (in NMath.dll) Version: 5.1.0.0

Syntax

C#
public class FourParameterLogisticFtn : DoubleParameterizedFunction
Visual Basic (Declaration)
Public Class FourParameterLogisticFtn _
	Inherits DoubleParameterizedFunction

public ref class FourParameterLogisticFtn : public DoubleParameterizedFunction

Remarks

f(x) = p3 + (p0-p3)/(1 + (x/p2)^p1)
, where p0 is the value at 0, p1 is the slope factor, p2 is the mid-range value, and p3 is the value at infinity.
