Hi,
here are three results of random forest (version 4.0-1).
The results seem to be more or less the same which is strange because I
changed the classwt.
I hoped that for example classwt=c(0.45,0.1,0.45) would result in fewer
cases classified as class 2. Did I understand something wrong?
The classwt are used in the gini index for splitting nodes. What we have
found (about two years ago) is that that option does not affect the
prediction as much as one would expect. I suspect the problem is because
the trees are grown to maximum sizes and not pruned back. This is why I

The common arithmetic operators such as ^ operate on the elements of
