Normalization by Subtracting the Mean 


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. The remaining variables in the rows are normalized in the same way.

The normalized value of ei for variable E in the ith row is calculated as:

where

n = the total number of rows in the data.
