Analysing a preference and approval profile

Abstract. This paper illustrates on two examples the use of some multivariate statistical analysis methods for describing profiles of preferences. The first example is the Social Choise and Welfare council election of 1999 and the second is a school-case fictious one. The school case example shows how these methods are able to discover structures on the sets of alternatives and voters. The real-life example shows that essentially the same findings obtain even when only approval votes (and not rankings) are available.
