Taxonomic Uncertainty on Multivariate Analyses of Ecological
Data
Permutational method to incorporate taxonomic uncertainty  and some functions to assess its effects on parameters of some widely used multivariate methods in ecology, as explained in Cayuela et al. (2011) <doi:10.1111/j.1600-0587.2009.05899.x>.

Beta regression for modeling beta-distributed dependent
variables, e.g., rates and proportions. In addition to maximum
likelihood regression (for both mean and precision of a
beta-distributed response), finite mixture models and recursive
partitioning for beta regressions are provided.
