Figure 6From: Hierarchical Cluster-based Partial Least Squares Regression (HC-PLSR) is an efficient tool for metamodelling of nonlinear dynamic modelsClustering results used in HC-PLSR for the mammalian circadian clock state variable M p . The global first three PLSR X-scores (PC1-PC3) obtained for the calibration set data for the mammalian circadian clock state variable MP. The observations are coloured according to the two-cluster solution used in the HC-PLSR (blue: cluster 1, red: cluster 2).Back to article page
