Correlation loading plot of PLS2 (X: NMR variables, Y: selected proteomic spots). Correlation loading plot (1^st and 2^nd PLS component) of PLS2 using NMR variables as X and selected proteomic spots as Y. Jack knifing has been applied to eliminate insignificant variables. The inner and outer ellipses refer to 50 percent and 100 percent explained variance in X and Y, respectively. The validated explained variances are 100%/0% for X and 51%/18% for Y, the 1^st and the 2^nd component, respectively.
