Namespace: Numerics.NET.Statistics
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.9.0

Overload List

KernelDensityGridOptions(Int32, Nullable<Double>, Nullable<Double>, Double)	Initializes direct grid evaluation settings.
KernelDensityGridOptions(KernelDensityFftOptions, Int32, Nullable<Double>, Nullable<Double>, Double)	Initializes grid settings with optional Gaussian FFT approximation.

KernelDensityGridOptions(Int32, Nullable<Double>, Nullable<Double>, Double)

Initializes direct grid evaluation settings.

public KernelDensityGridOptions(
	int pointCount = 512,
	double? lowerBound = null,
	double? upperBound = null,
	double padding = 3
)

Visual Basic

Public Sub New ( 
	Optional pointCount As Integer = 512,
	Optional lowerBound As Double? = Nothing,
	Optional upperBound As Double? = Nothing,
	Optional padding As Double = 3
)

C++/CLI

public:
KernelDensityGridOptions(
	int pointCount = 512, 
	Nullable<double> lowerBound = nullptr, 
	Nullable<double> upperBound = nullptr, 
	double padding = 3
)

new : 
        ?pointCount : int * 
        ?lowerBound : Nullable<float> * 
        ?upperBound : Nullable<float> * 
        ?padding : float 
(* Defaults:
        let _pointCount = defaultArg pointCount 512
        let _lowerBound = defaultArg lowerBound null
        let _upperBound = defaultArg upperBound null
        let _padding = defaultArg padding 3
*)
-> KernelDensityGridOptions

Parameters

pointCount Int32 (Optional): The number of output points, including both endpoints. Must be at least 2. The default is 512.
lowerBound Nullable<Double> (Optional): The finite lower evaluation bound, or null for the sample minimum minus padding times bandwidth.
upperBound Nullable<Double> (Optional): The finite upper evaluation bound, or null for the sample maximum plus padding times bandwidth.
padding Double (Optional): The finite nonnegative padding in adjusted bandwidths, used for unspecified bounds. The default is 3.

Remarks

Uses direct evaluation with no binning or tail truncation.

Exceptions

ArgumentOutOfRangeException	The point count, an explicit bound or padding is invalid.
ArgumentException	Both bounds are supplied but their difference is not finite and positive.

KernelDensityGridOptions(KernelDensityFftOptions, Int32, Nullable<Double>, Nullable<Double>, Double)

Initializes grid settings with optional Gaussian FFT approximation.

public KernelDensityGridOptions(
	KernelDensityFftOptions? fftOptions,
	int pointCount = 512,
	double? lowerBound = null,
	double? upperBound = null,
	double padding = 3
)

Visual Basic

Public Sub New ( 
	fftOptions As KernelDensityFftOptions,
	Optional pointCount As Integer = 512,
	Optional lowerBound As Double? = Nothing,
	Optional upperBound As Double? = Nothing,
	Optional padding As Double = 3
)

C++/CLI

public:
KernelDensityGridOptions(
	KernelDensityFftOptions^ fftOptions, 
	int pointCount = 512, 
	Nullable<double> lowerBound = nullptr, 
	Nullable<double> upperBound = nullptr, 
	double padding = 3
)

new : 
        fftOptions : KernelDensityFftOptions * 
        ?pointCount : int * 
        ?lowerBound : Nullable<float> * 
        ?upperBound : Nullable<float> * 
        ?padding : float 
(* Defaults:
        let _pointCount = defaultArg pointCount 512
        let _lowerBound = defaultArg lowerBound null
        let _upperBound = defaultArg upperBound null
        let _padding = defaultArg padding 3
*)
-> KernelDensityGridOptions

Parameters

fftOptions KernelDensityFftOptions: Explicit approximation controls, or null for direct evaluation. FFT requires the built-in Gaussian kernel.
pointCount Int32 (Optional): The number of output points, including both endpoints. Must be at least 2. The default is 512.
lowerBound Nullable<Double> (Optional): The finite lower evaluation bound, or null for the sample minimum minus padding times bandwidth.
upperBound Nullable<Double> (Optional): The finite upper evaluation bound, or null for the sample maximum plus padding times bandwidth.
padding Double (Optional): The finite nonnegative padding in adjusted bandwidths, used for unspecified bounds. The default is 3.

Remarks

FFT approximation is explicitly requested and never substituted for direct evaluation by default. Output point count is independent of internal FFT resolution. Bounds control evaluation, not statistical support.

Exceptions

ArgumentOutOfRangeException	The point count, an explicit bound or padding is invalid.
ArgumentException	Both bounds are supplied but their difference is not finite and positive.
