Detailed Description

Abstract base clase for adjusting the weight function bandwidth near the boundaries by keeping the value of a certain criterion constant. Usually, this criterion is some kind of a functional (e.g., the standard deviation of the weight function) which can be changed by increasing the bandwidth.

Constructor & Destructor Documentation

AbsBoundaryFilter1DBuilder()

npstat::AbsBoundaryFilter1DBuilder::AbsBoundaryFilter1DBuilder	(	const AbsDistribution1D *	distro,
		double	centralStepSize,
		const unsigned char *	exclusionMask = 0,
		unsigned	exclusionMaskLen = 0,
		bool	excludeCentralPoint = false
	)

This class will not own the AbsDistribution1D object. It is the responsibility of the user of this class to make sure that the AbsDistribution1D object stays alive while this object is in use.

It will be assumed that the distribution is symmetric about x = 0.0.

Member Function Documentation

centralWeightLength()

virtual unsigned npstat::AbsBoundaryFilter1DBuilder::centralWeightLength ( ) const

inlinevirtual

Length of the filter constructed at a point deeply inside the density support region

Implements npstat::AbsFilter1DBuilder.

isFolding()

virtual bool npstat::AbsBoundaryFilter1DBuilder::isFolding ( ) const

pure virtual

Return "true" for methods which fold the weight function at the boundary

Implemented in npstat::FoldBwFilter1DBuilder, npstat::ConstBwFilter1DBuilder, npstat::FoldingVarFilter1DBuilder, npstat::ConstVarFilter1DBuilder, npstat::FoldingSqFilter1DBuilder, npstat::ConstSqFilter1DBuilder, npstat::StretchingFilter1DBuilder, npstat::FoldingFilter1DBuilder, and npstat::TruncatingFilter1DBuilder.

keepAllFilters()

virtual bool npstat::AbsBoundaryFilter1DBuilder::keepAllFilters ( ) const

inlinevirtual

Should we keep all filters or can we assume that filters deeply inside the density support region are identical?

Implements npstat::AbsFilter1DBuilder.

lastBandwidthFactor()

virtual double npstat::AbsBoundaryFilter1DBuilder::lastBandwidthFactor ( ) const

inlinevirtual

"lastBandwidthFactor" will be meaningfully defined after calling the "makeOrthoPoly" method

Reimplemented from npstat::AbsFilter1DBuilder.

makeOrthoPoly()

virtual OrthoPoly1D* npstat::AbsBoundaryFilter1DBuilder::makeOrthoPoly ( unsigned  maxDegree, unsigned  binnum, unsigned  datalen, unsigned *  filterCenter  ) const

virtual

Build the orthogonal polynomial system that can later be used to construct filters with different tapers. This is constructed on the heap and later must be deleted.

Implements npstat::OrthoPolyFilter1DBuilder.
