Comparison of Attenuated Total Reflectance Mid-Infrared, Near Infrared, and ¹H-Nuclear Magnetic Resonance Spectroscopies for the Determination of Coffee’s Geographical Origin

Figure 5

Scores plots of typical models for discrimination by origin. These models were chosen from the top of the curves in Figure 4 (left). By “typical” we mean that their values are the most frequent over the 100-model sample generated in the Monte Carlo validation. Black squares: Colombia and white squares: other countries.
