Visual Basic

Public Shared Function FitReflected ( 
	input As Vector(Of Double),
	support As Interval(Of Double),
	Optional options As KernelDensityOptions = Nothing,
	Optional weights As Vector(Of Double) = Nothing
) As KernelDensityEstimate

C++/CLI

public:
static KernelDensityEstimate^ FitReflected(
	Vector<double>^ input, 
	Interval<double> support, 
	KernelDensityOptions^ options = nullptr, 
	Vector<double>^ weights = nullptr
)

static member FitReflected : 
        input : Vector<float> * 
        support : Interval<float> * 
        ?options : KernelDensityOptions * 
        ?weights : Vector<float> 
(* Defaults:
        let _options = defaultArg options null
        let _weights = defaultArg weights null
*)
-> KernelDensityEstimate

Parameters

input Vector<Double>: Nonempty finite observations inside the closed support, including zero-weight entries.
support Interval<Double>: The closed half-line or finite-interval support.
options KernelDensityOptions (Optional): Gaussian bandwidth options in original units, or null for normal-reference selection.
weights Vector<Double> (Optional): Optional finite nonnegative relative masses, paired by position with positive total mass.

Return Value

KernelDensityEstimate
An immutable reflected fit owning observation and weight snapshots.

Remarks

Finite endpoints are accepted. Selection uses the original observations before reflection. Finite intervals repeatedly fold all Gaussian mass into the support, including for wide bandwidths.

Exceptions

ArgumentNullException	The observations are null.
ArgumentException	Observations or weights are invalid, selection has insufficient spread, or the bandwidth cannot be resolved.
ArgumentOutOfRangeException	The support is unordered, has no finite endpoint, contains NaN or has unrepresentable finite width.
NotSupportedException	The kernel is not the built-in Gaussian kernel.
