An attribute with k values is transformed into k binary attributes if the class is nominal (using the one-attribute-per-value approach). Binary attributes are left binary, if option '-A' is not given.If the class is numeric, k - 1 new binary attributes are generated in the manner described in "Classification and Regression Trees" by Breiman et al. (i.e. taking the average class value associated with each attribute value into account)<br/> <br/> For more information, see:<br/> <br/> L. Breiman, J.H. Friedman, R.A. Olshen, C.J. Stone (1984).
