Normalization

A normalization transformation scales continuous (numerical) values to the range -1.0 to 1.0 or the range 0.0 to 1.0. A normalization transformation is of the form xnew=((xold-shift)/scale). Normalization applies to numerical attributes only.

Oracle Data Miner supports the following normalization schemes:

If you select Min-Max, you can specify the Min (minimum) and Max (maximum) of the normalized distribution; the defaults are 0 for the minimum and 1 for the maximum.
