The selection of this wavenumber was
based on the optimization process, i.e. the used wavenumber offered
the best prediction model for the relationship between actual value of
lard and FTIR predicted values. Besides, this wavenumber also gave
the highest coefficient of determination (R2) and the lowest values
of errors in calibration and prediction, expressed with root mean
square error of calibration (RMSEC) and prediction (RMSEP).
