Type 4 regression tree

[2min...@gmail.com]

Hi everyone,

my data are a numeric response variable, and categorical predictors (SNP genotypes). However, when I use the --treetype=4 option (which seems to be the correct choice according the the user manual), the importance file contains only zero values. In addition, the header is "gini_index", while I expected "SS_decrease" because my response variable is continuous ...

Did anybody has the same problem, and got any solution?

Thank you by advance,
Benjamin
