Thanks for the reply! However, what is the code that is used in order to
calculate it.. Is it included in the "randomForest" R function.. Because I
am trying to find the code corresponding to the estimation of the gini
coefficient but I am a bit confused. Could you please help me, by indicating
me that?

thanks a lot,

chrysanthi
