Soil Compositions of Physical and Chemical Characteristics
Soil characteristics were measured on samples from three types of contours (Top, Slope, and Depression) and at four depths (0-10cm, 10-30cm, 30-60cm, and 60-90cm). The area was divided into 4 blocks, in a randomized block design. (Suggested by Michael Friendly.)
These data provide good examples of MANOVA and canonical discriminant analysis in a somewhat
complex multivariate setting. They may be treated as a one-way design (ignoring
by using either
Gp as the factor, or a two-way randomized block
Depth (quantitative, so orthogonal
polynomial contrasts are useful).
