TABLE VI.- Classification obtained by linear discriminant analysis on carcinogenic activity study : (compounds cataloged on Merck Index). C = high expectancy of being carcinogenic (>90%) ; PC = probable carcinogenic activity (between 70% and 90%) ; I = high expectancy of being non carcinogenic(>90%); PI = probable non carcinogenic activity (between 70% and 90%); U = non classified. 3,4-diaminopyridine 2.34 C Compound DFcarc Class. 3,4-dichloroaniline 2.13 C 3,5-dibromo-l-tyrosine -0.54 U 1,1,2-trichloroethane 5.30 C
