NMathFunctionsFourParameterLogisticFtnEvaluate(DoubleVector, Double) Method

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

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public override double Evaluate(
	DoubleVector parameters,
	double x
)

Public Overrides Function Evaluate ( 
	parameters As DoubleVector,
	x As Double
) As Double

public:
virtual double Evaluate(
	DoubleVector^ parameters, 
	double x
) override

abstract Evaluate : 
        parameters : DoubleVector * 
        x : float -> float 
override Evaluate : 
        parameters : DoubleVector * 
        x : float -> float

Parameters

parameters DoubleVector: The parameter values.
x Double: The point to evaluate the function at.

Return Value

Double
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.
