Comparison of population distribution. Normalized population distributions of major cell wall sugars from the experimentally determined Mahalanobis distance and PLS model outliers. The PLS model outliers display a shifted distribution for increased sugar differences for Gal, Gla and Xyl. PLS modeling of cell wall sugar composition provides a smaller and more selective cohort of possible outliers enriched in monosaccharide differences compared to using Mahalanobis distance alone.
