ABSTRACT
Simultaneous quantification of rows and columns of a two-waydata table has a long history. When we look at it, we cannot help but wonder why a number of researchers have developed essentially the same method under different names, often being unaware of other relevant studies. A reason for this peculiarity perhaps lies first in the fact that there are many ways to formulate the method and second in the fact that the problem of quantification has attracted the attention of researchers in diverse fields of research in many countries. As for the first fact, Greenacre (2005) discussed thirteen ways to formulate “correspondence analysis,” one of many names of MUNDA. As for the second fact, it must strictly be due to the point that categorical data are ubiquitous in many fields and many countries.
