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: 7.3
Syntax
Copy
public override double Evaluate(
	DoubleVector parameters,
	double x
)

Parameters

parameters
Type: CenterSpace.NMath.CoreDoubleVector
The parameter values.
x
Type: SystemDouble
The point to evaluate the function at.

Return Value

Type: 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.
