It is especially important in factor analysis of mixed data (FAMD) and in multiple factor analysis (MFA). == Definition of ''relationship square'' in the MCA frame == The first interest of the relationship square is to represent the variables themselves, not their categories, which is all the more valuable as there are many variables.
