at the specified point.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static double FourParameterLogistic(
DoubleVector p,
double x
)
Public Shared Function FourParameterLogistic (
p As DoubleVector,
x As Double
) As Double
public:
static double FourParameterLogistic(
DoubleVector^ p,
double x
)
static member FourParameterLogistic :
p : DoubleVector *
x : float -> float
Parameters
- p DoubleVector
- The function parameters.
- x Double
- The point at which to evaluate the function.
Return Value
DoubleThe value of the function evaluated at x.
Exceptions 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.
