Function Documentation

BaselineAsLS()

const std::vector< double > sablib::BaselineAsLS	(	std::vector< double > &	y,
		const double	lambda,
		const double	p,
		const unsigned int	s = 2,
		const unsigned int	loop = 10,
		const double	eps = 1e-3 )

Performs baseline estimation using Asymmetric Least Squares Smoothing (AsLS).

Parameters

y	The input data for baseline estimation.
lambda	Smoothing parameter.
p	Weight (asymmetry parameter, typically 0.001 to 0.1).
s	The order of the difference (usually s = 1, 2, or 3).
loop	Maximum number of iterations.
eps	Convergence threshold.

Returns

The estimated baseline.

Exceptions

std::invalid_argument

One or more parameters are wrong.
