principal component analysis
peakomponentide meetod
olemus
meetod tugevate mustrite leidmiseks uuritavas andmekogumis
(K. Pearson, 1901), hõlbustab andmete uurimist ja
visualiseerimist, võimaldab vähendada mõõtmelisust;
teisendab andmed, milles on korreleeritud muutujaid,
saades korreleerumata muutujad, st peakomponendid
= a statistical procedure that allows to summarize the information content in large data tables by means of a smaller set of summary indices that can be more easily visualized and analyzed
