LDA provides class separability by drawing a decision region between the different classes.

WebLDA has 2 distinct stages: extraction and classification. At extraction, latent variables called discriminants are formed, as linear combinations of the input variables. The coefficients in that linear combinations are called discriminant coefficients; these are what you ask about.
