What is new in Mstrat4.0 ?

The new version accepts missing data.

When different samples have the same richness, a second criteria of optimization is used. Three criteria are proposed : Nei indice, Shannon indice, and generalized variance. For the generalized variance criteria, a principal component analysis is performed with R software on complete data file.
