1.9 Summary

A framework has been outlined of three categories of technique (univariate, graphical/distributional and multivariate) and four analysis stages (representing communities, discriminating sites/conditions, determining levels of stress and linking to environmental variables). The most powerful tools are in the multivariate category, and those that underlie the PRIMER routines are now examined from first principles.
