type ScalingMethod

None	0	No scaling is performed.
UnitVariance	1	The columns are scaled to have unit variance.
VectorNorm	2	The columns are scaled to have unit norm.
Pareto	3	The columns are scaled by the square root of the standard deviation.
Range	4	The training columns are scaled to the nominal interval [0, 1], or [-1, 1] when centered about the fitted midpoint. New observations use the same affine transformation and may fall outside this interval; values are not clipped.
Level	5	The columns are scaled by the column mean.
MaxNorm	6	The training columns are scaled by their maximum absolute value, or by their maximum absolute deviation from the fitted mean when centered. New observations use the same affine transformation and may have absolute values greater than 1; values are not clipped.
