Normalization by Signed Ratio 


Assume that there are n rows with seven variables, A, B, C, D, E, F and G, in the data. We use variable E as an example in the calculations below. All target variables are normalized in the same way.

If we select A as baseline variable, the normalized value of ei for variable E in the ith record is calculated as:

if ei > ai

images/n_signed_ratio_ekv_2.gif

if ei < ai

where

ai = the value for variable A in the ith row.
