(Sample linear discriminant analysis) Let and be the following 14 x 1 vectors: (a) (b) (c) (d) iid 41), a sample Y], , iid 41) and Draw a sample X 1, . a sample , Zs iid IVId(ga, 41). These samples give you a data matrix for each of three classes C, , C2 and C3. Write the formulas you will use to compute Be and The kth sample discriminant of a point zr is Yk = Wk x. How is Wk defined? Make a plot of all the data on the first tux) discriminants using different colors for each of the three classes.
