Difference between CRIT and previous techniques. (a) Data in a single matrix can be investigated using techniques such as PCA. Techniques such as CCA are applicable to two matrices with a common index. CRIT allows working with three or more matrices that do not share a common index. (b) An overview of CRIT. (c) A simple example showing how proteins can be labeled as sensitive to a particular drug property. See text for more details.
