Influence of Normalization on Arrangement of Objects in Synthetic Comparative Researches
Languages of publication
The paper presents considerations concerning the influence of normalizing the diagnostic variables with constant parameters on the arrangement of objects in synthetic comparative researches. There is proved that if we know values of the diagnostic variables and the normalization parameters we can predict the arrangement of objects depending on the values of the synthetic variable. The examples show that we may get different arrangements depending on the kind of used normalization. In other words, we may have an effect on the arrangement of objects by the choice of the normalization parameters. The considerations lead to the following conclusion: each arrangement of objects depending on the values of the synthetic variable is subjective. It depends on knowledge and experience of the explorer, who makes the choice of the normalization method.
