tecator data

Description

Water, Fat and Protein content of meat samples

Format

The format is:
..$absorp.fdata: absorbance data. fdata class object with:

• "data": Matrix of class fdata with 215 curves (rows) discretized in 100 points or argvals (columns).
  

• "argvals": 100 discretization points from 850 to 1050nm
  

• "rangeval"=(850,1050): range("argvals")

• "names" list with: main an overall title "Tecator data set", xlab title for x axis "Wavelength (nm)" and ylab title for y axis "Absorbances".

..$y: the percentages of Fat, Water and Protein. The three contents are determined by analytic chemistry.

Details

absorp.fdata absorbance data for 215 samples. The first 129 were originally used as a training set endpoints the percentages of Fat, Water and Protein.
