Claim 0:
1. A method of smoothing spectral data recorded by a spectrometer, the method comprising:
successively fitting a plurality of spline curves to the spectral data,
each spline curve having a different number of knots, and
a knot position of each knot, other than end point knots, in each spline curve being determined based upon a measure of fit to the spectral data of points of a previously fitted one of the plurality of spline curves having fewer knots;

selecting one of the spline curves as a smoothed data curve of the spectral data based upon a model selection criterion;
analyzing the smoothed data curve to identify a property of a sample that generated the spectral data; and
controlling a process and/or carrying out further processing on the sample based upon the identified property.
