Only Table 3 prints numbers: 'marginal prices' in euro (per unit of an ordinal score) for the variables Location and State of building in the four Taranto zones, with p-values; the scoring scale of the ordinal variables is not given and the paper tested both linear and log-linear forms without stating which was retained (marginal price = coefficient only in the linear model), so dep_transform is recorded as 'other' and confidence is low. Adjusted R2 from Table 2. Table 4 only lists which variables were significant per zone (floor area always significant; orientation never). Property type not stated (variables such as floor level with elevator and balconies suggest apartments)."
