Abstract: Problem nedostajućih podataka dosta je prisutan kod anketnog istraživanja. Ukoliko se ne utvrdi tip mehanizma nedostajućih podataka, ocene nepoznatih parametara analiziranog statističkog modela, mogu biti pristrasne. Data neželjena osobina, može se prevazići pravilnim tretiranjem nedostajućih podataka, među kojima je svakako upotreba EM algoritma.
