Plots of 20 most dominant spectral features (wave numbers) influencing model prediction of Plasmodium-infection status of the dried blood spot specimens. The positive coefficients are those most predictive of Plasmodium positive specimens while the negative coefficients are those most predictive of Plasmodium-negative specimen. All the top 20 features are found in the fingerprint region (1730 cm⁻¹–883 cm⁻¹)
