| الوصف: | Questo articolo presenta un nuovo approccio al clustering bidimensionale nell’ambito dei preference-approval. Il metodo proposto utilizza la tecnica dell’unfolding per stimare le coordinate di un insieme di m individui e di un insieme di n alternative in uno spazio p-dimensionale basato sui loro valori di prossimit`a La principale innovazione dell’approccio `e la produzione di una rappresentazione grafica che cattura contemporaneamente le relazioni sia tra gli individui che gli oggetti. Viene proposta un’applicazione del metodo a dati reali, provenientei sito Eurobarometer. La nostra analisi ha rivelato l’esistenza di due cluster di paesi con preferenze simili, con alcuni paesi che hanno preferenze miste o uniche. ; This paper presents a novel approach to two-dimensional clustering within a preference-approvals framework. The proposed method employs the ordinal unfolding technique to estimate the coordinates of a set of m individuals and n alternatives in a p-dimensional space based on their proximity values. The main contribution of the approach is the production of a graphical representation that simultaneously captures both individuals and alternatives. To explore the implications of the proposed method, we utilize Eurobarometer data poll. Our goal is to identify common patterns of preferences among individuals and alternatives. The analysis reveals the existence of two main clusters of countries with similar preferences, with some countries having mixed or unique preferences. |
