Hi,
The Decision Tree Learner offers the possibiliy to yes or no use a pruning option. I would also like te be able to use specific stopping rules based on purity/homogeneity or significance measures. That would allow me to fine tune the model better. In some analyses so far I have observed either too small (pruned) trees or too large (unpruned) trees (as compared to acceptable trees made with R or SPSS).
Thanks, Kees
