Discriminant analysis
WebDiscriminant analysis (DA) is a multivariate technique used to separate two or more groups of observations (individuals) based on variables measured on each experimental unit (sample) and find the contribution of each variable in separating the groups. DA works by finding one or more linear combinations of the selected variables. http://personal.psu.edu/jol2/course/stat597e/notes2/lda.pdf
