"WebAs noted by Anderson (2001), ecological data sets rarely conform to the assumptions of MANOVA-like procedures (see MANOVA).For example, rare species inflate the data set with zeros while species with low abundances are unlikely to be normally distributed (the "bell-shaped" curve will be 'cut' at zero, resembling a Poisson distribution with λ ~ 1).
