Abstract
A method of smoothing spectral data recorded by a spectrometer including successively fitting a plurality of spline curves to the spectral data, each spline curve having a different number of knots. A knot position of each knot, other than end point knots, in each spline curve is determined based upon a measure of fit of points of a previously fitted one of the spline curves having fewer knots to the spectral data. The method further includes selecting one of the spline curves as a smoothed data curve of the spectral data based upon a model selection criterion.
