Constructor & Destructor Documentation

Smoother() [1/2]

theplu::yat::statistics::Smoother::Smoother	(	const regression::Kernel &	,
		double	width,
		const std::vector< double > &	values
	)

Constructor taking vector describing for which values distribution should be estimated.

Note

if values are not sorted the behavior is undefined

Smoother() [2/2]

theplu::yat::statistics::Smoother::Smoother	(	const regression::Kernel &	kernel,
		double	width,
		double	xmin,
		double	xmax,
		size_t	n
	)

Constructor creating observation points equally distributed between xmin and xmax.

Parameters

kernel	doing the smoothing
width
xmin	smallest observation point
xmax	largest observation point
n	number of observation points
