⚠️There's a newer version (2.4.1) of this package.Take me there.

robCompositions (version 1.3.2)

Robust Estimation for Compositional Data.

Description

The package includes methods for imputation of compositional data including robust methods, (robust) outlier detection for compositional data, (robust) principal component analysis for compositional data, (robust) factor analysis for compositional data and (robust) Anderson-Darling normality tests for compositional data as well as popular log-ratio transformations (alr, clr, ilr, and their inverse transformations).
