Hi,
I am a student and I am starting to use R. I have a question regardint
the Data mining - rattle package.
Once I create a decission tree (predictive) I want to evaluate it.
Under the "evaluate" option I can choose between:
"Pr v Ob": I do not know how to interpret the Pseudo R square value
obtained (0.7) because I do not know which measure or definition of
pseudo R -square the program uses and therefore the bounds of the
value that can be obtained. can anyone hekp me, please?
"Risk": Similar question but for the adjustment value and the graph obtained.
Thank you very much
