Details
The maximum a' posteriori (MAP) tree encountered at each height
(in the MCMC chain) is plotted, and the log posterior probabilities
are shown for comparison. The text at the branches in the tree show
the splitting variable and value. The text at the leaves show the
number of input data points (X
and Z
) that fall
into the region(s) along with an estimate of the variability therein.
Value
The only output of this function is beautiful tree diagrams.
Note
Plotting trees that the maptree library is installed, which itself requires that the combinat library also be installed.
