MCDMRegression evaluation

R-kvadrat (R²)

Koeficijent determinacije, označen s R², mjeri udio varijance zavisne varijable objašnjen nezavisnim varijablama u regresijskom modelu. Uveo ga je Karl Pearson krajem 19. stoljeća, a R² je jedna od najčešće korištenih metrika za procjenu koliko dobro model pristaje promatranim podacima.
