Sažetak
Multivariate chemometric techniques (principal component analysis, factor analysis, feature selection) have been applied to thermodynamic data of equilibria in different solvents. Eight fundamental reactions in various water-cosolvent mixtures have been considered, at 20 °C (63 equilibria in total). Possible advantages deriving from these techniques, in comparison with the use of traditional univariate methods, are briefly examined. In particular, it is shown that two factors account for 97.8% of variance in the data.
