partition {tgp} | R Documentation |
Partition data according to the maximum a' posteriori (MAP)
tree contained in a "tgp"
-class object.
partition(X, out)
X |
data.frame , matrix , or vector of inputs X
with the same dimension of out$X , i.e., dim(X)[2] == dim(out$X)[2] |
out |
"tgp" -class object which is the output of one
the model functions with tree support (e.g. btgpllm ,
btgp , btlm , or tgp ) |
Output is a list of data.frame
s populated with the inputs
X
contained in each region of the partition of the MAP tree
in the "tgp"
-class object out
