"WebLet's start with finding one direction which maximizes this ratio. And we will assume the within-class covariance matrix of X is W, i.e., the common covariance matrix of the classes (computed by LDA). Then we would also need a between-class covariance matrix denoted by B. This is the covariance matrix you compute using only the mean vectors. " - Fisher matrix analysis
