Received: 17 November 2011; in revised form: 20 February 2012 / Accepted: 20 February 2012 / Published: 29 February 2012 Abstract: In this note we illustrate and develop further with mathematics and examples, the work on successive standardization (or normalization) that is studied earlier by the same authors in [1] and [2]. Thus, we deal with successive iterations applied to rectangular arrays of numbers, where to avoid technical difficulties an array has at least three rows and
