Which is the final model for a Boosted Regression Trees (GBM)?
...d values but I wanted to calculate the fitted value by hand to understand in depth. Would you give moe some hints on what is the final model for this example?
Thanks

gbm error
Good afternoon
Has anyone tried using Dr. Elith's BRT script? I cannot seem to run
gbm.step from the installed gbm package. Is it something external to gbm?

gbm.x = colx:coly,
gbm.y = colz,
family = "bernoulli",
tree.complexity = 5,
learning.rate = 0.01,
bag.fraction = 0.5)
