Evaluates the four parameter logistic function for the given parameter values at the given point.

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

Syntax

C#
public override double Evaluate(
	DoubleVector parameters,
	double x
)
Visual Basic (Declaration)
Public Overrides Function Evaluate ( _
	parameters As DoubleVector, _
	x As Double _
) As Double
Visual C++
public:
virtual double Evaluate(
	DoubleVector^ parameters, 
	double x
) override

Parameters

parameters
Type: CenterSpace.NMath.Core..::.DoubleVector
The parameter values.
x
Type: System..::.Double
The point to evaluate the function at.

Return Value

The function value for the given parameter values at the the given point.

Remarks

y = 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.
