0461. R za finansije

Kurs R: From Zero to Hero osmišljen je za sve koji žele da savladaju rad u programskom jeziku R od samih osnova do naprednijih tehnika analize podataka. Kroz jasno strukturirane lekcije naučićeš kako da efikasno vršiš manipulaciju podataka, organizuješ skupove podataka i pripremaš ih za dalju obradu. Poseban fokus stavljen je na vizuelizaciju podataka uz pomoć biblioteke ggplot, gde ćeš naučiti kako da kreiraš profesionalne i pregledne grafike. Takođe, kurs pokriva osnove prediktivne analize, uključujući rad sa modelima poput regresije (reg1, reg2 i slični pristupi). Sve lekcije su praktično orijentisane, uz konkretne primere iz realnog sveta. Na kraju kursa bićeš spreman da samostalno analiziraš podatke i donosiš informisane zaključke koristeći R.
