Cumulative canonical correlation showing the increasing amount of variance accounted for by each gene in the discriminant model.
To classify an observation (x) into one of the groups, the discriminant score [D2y (x)] is calculated for each group (y) using the above functions. These scores are inversely related to the distance that observation is from the middle of each group. The observation belongs to the group whose function gives the highest discriminant score. The probability of an observation (x) belonging to a group (y) is calculated as eDy2(x)/[eDControl2(x)+eDINH2(x)+eDTLM2(x)+eDTRC2(x)].
