ABSTRACT
Contingency data are represented as a table of m rows by n columns of response frequencies or presence or absence of responses. The following is an example of a 3x6 table, which lists sales of three kinds of barley (A-C) at six super-markets in the past one month, the unit being a 500 gram bag. Although the above example is a typical one, we also have the following
Barley Store1 Store2 Store3 Store4 Store5 Store6
A 46 57 83 87 6 62 B 4 34 35 19 4 34 C 13 9 15 58 0 1
type. Suppose children were asked to check which features the animals they saw today at the zoo had. The quantification task is to determine weights for rows and those for columns of the table in such a way that joint frequencies are best explained.
