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 ---------------------------------------------------------------- Este mensaje ha sido enviado desde https://webmail.unav.es
