Discriminant analysis has been employed by researchers in automatic text genre detection ( Biber 1993b ; Karlgren and Cutting 1994 ) since it offers a simple and robust solution despite the fact that it presupposes normal distributions of the discriminating variables .

where C , is the covariance matrix of x. Using this classification method we can also derive the probability that a case belongs to a particular group ( i.e. , posterior probabilities ) , which is roughly proportional to the Mahalanobis distance from that group centroid .
