The weights don't have to sum up to one. These are the weights of the
trees in the bag used to combine them into the final fit, and if I'm
not mistaken expressed as the logit of the error for the respective
If you use a method, be sure you understand it. If you don't
understand those weights, I reckon there's a whole lot of other things
you don't understand about the method. A good start is running and
analyzing the example in the help file. Those weights don't sum up to
one either, but the authors don't seem to mind...
There are references given in the help files, and you should
understand what they say before you apply the algorithm. You're not
going to handle a chainsaw without reading the manual carefully
