Multivariate Random Forest with Compositional Responses

Multivariate random forests with compositional responses and Euclidean predictors is performed. The compositional data are first transformed using the additive log-ratio transformation, or the alpha-transformation of Tsagris, Preston and Wood (2011), , and then the multivariate random forest of Rahman R., Otridge J. and Pal R. (2017), , is applied.
