From surface to core: A multi-layer approach for the real estate market analysis of a central area in Catania

The proposed study deals with the analysis of the real estate market in the quarter of San Cristoforo in Catania, trying to integrate different approaches to define its possible articulation in submarkets. The first one is a phenomenal type of approach that intends to represent some of the most manifest characteristics, and provides an initial hypothesis of classification of the cases (a census has been taken of) and delimitation of the segments, taking into account the ranges of prices registered inside the different classes of the characteristics. The second consists of an in depth clustering analysis basing on three different hypotheses of three, four and five clusters respectively. The third one is a DRSA application, which is meant to extract from the studied sample a set of rules for the possible definition of a segment representing the general market rules. Given the complexity of the studied context, the results allow different interpretations and considerations of method.
