Appraising property with rough set theory

This research is focused on a methodology created to analyse imprecise information, that is full of attributes defined as “rough set”. The methodology will be then applied to the real estate appraisal question, representing a further possible method of evaluation. Up to now the main approaches to the real estate appraisal have been income, market and cost. My intention is to analyse this theory showing a practical application on a group of real estate transactions made by a real estate agent. This application will show how it is possible to get values to classify a real estate. A comparison between this method and the most common statistics instruments will be highlighted.
