chemometrics (version 1.3.7)

NIR: NIR data

Description

For 166 alcoholic fermentation mashes of different feedstock (rye, wheat and corn) we have 235 variables (X) containing the first derivatives of near infrared spectroscopy (NIR) absorbance values at 1115-2285 nm, and two variables (Y) containing the concentration of glucose and ethanol (in g/L).
