NUMERICAL ANALYSIS OF A CHRONOSEQUENCE INCLUDING AN ASSESSMENT OF VARIABILITY
One hundred and eighty-three soil samples from 60 pits were collected from a sequence of moraines located in front of the Robson Glacier, Mt. Robson, British Columbia. Univariate analysis of variance, oblique rotation factor analysis, and nonlinear regression were employed to ascertain the major pro...
