Optimization by factorial design A factorial design with central point, three variables and three levels [low (-1); medium (0) and high (+1)] was done to check the influence of each studied variable and their simultaneous interactions in calcium determination in milk samples (Table 1).	cache/ecletica-999.pdf	txt/ecletica-999.txt
