Figure 5: The linear combinations (loadings and loading.weights respectively) of X (explanatory) and Y (response) variables are presented for each component.

Only variables that presented loadings or loading.weights >0.3 were represented. The contribution of each variable to the component (measured by variable of importance for the projection: VIP > 1) is highlighted by (*). The percentage of variance explained is represented in brackets. Comp = component, hab = habituation, pleas = pleasantness, int = intensity, fam = familiarity, Vp = vapour pressure, Mw = molecular weight, OAV = odor activity value, Db_bonds = double bonds, C_chain = carbon chain length, conf = number of conformers, logP = hydrophobicity, ASA_range = accessible surface area.
