R-kvadrat (R²)
Koeficijent determinacije, označen sa R², meri proporciju varijanse zavisne promenljive objašnjene nezavisnim promenljivama u regresionom modelu. Uveden od strane Karla Pirsona krajem 19. veka, R² je jedna od najčešće korišćenih metrika za procenu toga koliko dobro model odgovara posmatranim podacima.
