Divided by a Common Language: Analyzing and Visualizing Two-Way Arrays
Michael Greenacre, Jorg Blasius · 2006
According to George Bernard Shaw, the U.S. and the U.K. are two nations divided by a common language. I sometimes think that the range of data-analytical methods concerned with approximating two-way especially spectral decompositions and singular-value decompositions. This common mathematical foundation may be a powerful basis for writing unified software, but it can obfuscate the statistical interpretations appropriate to the different methods. In the following, I shall be concerned more with statistical differences than with computational similarities.
