R help - Jun 2013 - Package random forest: can corr.bias be harmful?

There exists an option corr.bias for making regression analyses with the 
R package randomForest. The manual warns ?Experimental. Use at your own 
risk.? What does corr.bias precisely do and why can it be dangerous to 
use it? As far as I know the bias correction is based on a linear 
regression between the out-of-bag-prediction and the observed values 
which is used for correction of all predictions made by the model, but 
this does not appear so harmful to me.

Hi, Christian.

It sounds like to the maintainer feels that the package needs improvements,
i.e., it may not function as expected.  However, you may contact him
directly using maintainer("randomForest").

Best,
Benjamin
