From the results table 7, it is found that, the presence of FDs on attribute A - F, B - F, D - F and E - F. The FD for A-F is 100 accurate where the G3 value is 0. And
B - F shows about 97 of accurate prediction of FDs. The other two FD predictions in between D - F and E - F does not showing precise prediction. Because D-F produced
G3 error of 0.42 which is about only 58 FD accuracy. Whereas E-F produced G3 error
48
of 0.64, about 36 FD accuracy. If the G3 value is near to zero than the prediction of FDs is 100 accurate.
