Dear friends,
I have just posted a question on the identification of plots-sites
in Multivariate Regression Trees produced by the mvpart package in R.
However, I figured it out that it is just to sort the data according
to the threshold values given by the resulting tree. Maybe there is a
function in mvpart to give this information, but data sorting seems to
work.
Yet, another question arose. De'ath (2002, Ecology) states that MRT
can be developed from other distance-based measures than the Euclidean
distances. Do anyone knows how to implement it using mvpart?
Best wishes,
Alexandre
