Below is a diagram of a multivariate analysis which used discriminate function analysis to attempt to determine the source of sediments in streams in Kenya. The data is based on chemical measurements from streams. Questions: 1) Do you think the diagrams support the conclusion of the authors that Agricultural land is the main source of sediment load? This is in part based on the grouping of the sources. 2) The results look very different in a and b what accounts for the difference? Do you think that excluding the unpaved track data is warranted or a method getting the results desired?
