Tecator data
Description
Fat, protein, and moisture content, along with absorbance spectra (including the first and second derivatives), of 215 meat samples. A detailed description of the data can be found at http://lib.stat.cmu.edu/datasets/tecator.
Usage
data(Tecator)Format
A list containing:
fat: A vector with the fat content.protein: A vector with the protein content.moisture: A vector with the moisture content.absor.spectra: A matrix containing the near-infrared absorbance spectra observed at 100 equally spaced wavelengths in the range of 850-1050nm.absor.spectra1: Fist derivative of the absorbance spectra (computed using B-spline representation of the curves).absor.spectra2: Second derivative of the absorbance spectra (computed using B-spline representation of the curves).
