Prune a cubt tree.
prune.cubt(trclust,Dt,mindist=NULL,qdist=0.8,alph=0.3,nleaves=NULL,dist= FALSE,...)
trclust |
A CUBT tree. |
Dt |
Data used to construct the tree |
mindist |
Minimum distance between adjacent leaves to be pruned. |
qdist |
quantile of distances over couples of nodes in the tree to use as mindist. |
alph |
The quantile used for computing distances. See definition of the distance in he original paper. |
nleaves |
Number of leaves desired after pruning. |
dist |
If true returns the distances computed all along the nodes. |
... |
Other possible parameters passed for distance computation |
Minimum dissimilarity pruning. Two adjacent nodes are pruned if their distance defined by Fraiman et al. is less than mindist. Mindist may be specified by the user as a threshold, if not a quantile qdist is used, and mindist will be taken to be the corresponding quantile of the observed distances in the tree.
