About this book
This edition includes increased coverage on measuring distances between cases based on on presence-absence data, a new section on logistic regression, new exercises and two completely new chapters on graphical methods and ordination. The author has taken into account the major shift in the way in which computer software is used. The emphasis is on the underlying principles rather than the use of particular programs.
