Correlation loadings for the mammalian circadian clock state variable M
. The global PLSR X- and Y-correlation loadings (P and Q, respectively) for PC1 to PC3 obtained for the calibration set data for the circadian clock state variable MP. X-loadings (model parameters) are shown as dots, while Y-loadings (time series) are shown as a curve. The loadings for the cross-terms and second order terms of the parameters are not shown in order to increase the overview.
