ABSTRACT
In all the examples and analyses presented so far, we have dealt with the analysis of the rows of a table, visualizing the row profiles and using the columns as reference points for the interpretation: let’s call this the “row analysis”. All this can be applied in a completely symmetric way to the columns of the same table. This can be thought of as transposing the table, making the columns the rows and vice versa, and then repeating all the procedures described in Chapters 2 to 7. In this chapter we shall show that the row analysis and column analysis are intimately connected. In fact, if a row analysis is performed, then the column analysis is actually being performed as well, and vice versa. Correspondence analysis (CA) can thus be regarded as the simultaneous analysis of the rows and columns.
