Hi, I am building a predictive model using a decision tree, the target is binary (5.8% of the population) and there are both numeric and nominal explanatory variables. Once i build the model using the automatic mode i find that the result is blank i.e there is only the root node. I then tried building an interactive decision tree and found that the model was not able to predict many leavers. Has anybody come across a blank decision tree and does this imply something wrong with a setting/input data etc Regards Syed
