virtual unsigned	dataLen () const =0
virtual double	selfContribution (unsigned index) const =0

Detailed Description

Base class for LOrPE, etc. smoothers which can be later used with cross-validation algorithms. These algorithms usually work according to the "leaving-one-out" method, in which the contribution of one point into the density estimate must be subtracted. Therefore, this contribution must be known to begin with, and this is precisely the info this class is intended to convey.

Member Function Documentation

dataLen()

virtual unsigned npstat::AbsPolyFilter1D::dataLen ( ) const

pure virtual

Length of the data array

Implemented in npstat::LocalPolyFilter1D, npstat::ConstantBandwidthSmoother1D, npstat::ContribVector1D, and npstat::ContribConstant1D.

selfContribution()

virtual double npstat::AbsPolyFilter1D::selfContribution ( unsigned  index ) const

pure virtual

Contribution of a single point into the density estimate at that point (not normalized). This is needed for various leaving-one-out cross-validation procedures.

Implemented in npstat::ConstantBandwidthSmoother1D, npstat::ContribConstant1D, npstat::LocalPolyFilter1D, and npstat::ContribVector1D.
