Two software packages that do all multivariate analysis and are free are
and the BiodiversityR package for R
Both were designed for vegetation analsysis but do all sorts of
multivariate analysis including clustering and nometric
multidimensional scaling (NMDS) on a variety of similarity
measurements. Ginkgo is easier to use unless you are already familiar
with R. Both run under the most common operating systems.
