Variance importance plot (top) and regression parameter profile (bottom). This graph shows the variance importance plot (top) and regression parameter profile (bottom) after removing predictors with the VIP statistic of Wold of <0.8. The VIP statistic of Wold in the variance importance plot illustrates the contribution of each predictor in fitting the PLS model for both predictors and response, the most important serum proteins contributing to the PLS model. The regression parameter profile shows absolute coefficients for the centered and scaled parameter estimates. DASH, Dietary Approaches to Stop Hypertension; VIP, Variable Importance for Projection.
