dudi.fca
(Package: ade4) :
Fuzzy Correspondence Analysis and Fuzzy Principal Components Analysis
Theses functions analyse a table of fuzzy variables.
A fuzzy variable takes values of type a=(a1,…,ak) giving the importance of k categories.
A missing data is denoted (0,...,0).
Only the profile a/sum(a) is used, and missing data are replaced by the mean profile of the others in the function prep.fuzzy.var. See ref. for details.
● Data Source:
CranContrib
● Keywords: multivariate
● Alias: dudi.fca, dudi.fpca, prep.fuzzy.var

randEH
(Package: ade4) :
Nee and May's random process
When branch lengths in an ultrametric phylogenetic tree are expressed as divergence times, the total sum of branch lengths in that tree expresses the amount of evolutionary history. The function randEH calculates the amount of evolutionary history preserved when k random species out of n original species are saved.
