total intensity transformation paired
Philippe Rocca-Serra
A total intensity transformation paired is a data transformation that takes as input two n-dimensional (real) vectors and multiplies each component of the first vector by a coefficient, where the coefficient is obtained by taking the ratio of the sum of the second input components or of a subset of these by the sum of the first input components or of a subset of these (the same subset is used for the two vectors).

Note that if the word "sum" is replaced by the word "mean" in the definition, the resulting definition is equivalent.

This can be used as a simple normalization method for the two channels from a two-channel expression microarray assay or from two related one-channel expression microarray assays.
