Upper confidence limit 25% (U25%) for pruning the C4.5 decision tree (how in VB?)
Hi eveybody,
I'm almost finished implementing the C4.5 classification decision tree with VB6. Does anybody have any idea how to calculate the upper confidence limit 25% for the pruning process with VB? There are examples with Excel but I couldn't find any for VB. It's for a course project and the deadline is close, help please !! Smile  Sad

Thanks,
Anita
