assess the potential of developing regional scale versus site-specific postmanagement schemes using weather and site variation. In all these cases,
a simultaneous handling of several variables is required, and entails the
use of multivariate statistics such as discriminant analysis, multivariate
analysis of variance, correspondence analysis, and canonical correlation

with cited examples. vari...
