statistical computer programs are needed,
but they are not presented here. A descrip-
tion of multivariate approaches can be found
in Morrison (1990), Harris (2001), Tabachnick
and Fidell (2001) and Johnson and Wichern
(2002); Tabachnick and Fidell (2001) can be
recommended because of its practical
approach.314 E. Wajnberg
