The 'beta' recorded below is the MEAN local coefficient; min/max are given in notes. These are not precision-weighted global estimates and should not enter the primary synthesis. Dependent variable: advertised price in EUR per m2 (level). Distances in metres; counts within 500 m. Table 3 (p. 10) gives summary statistics of significant local coefficients for environmental variables only (not extracted as model coefficients). Global R2 0.4090, adj 0.3616. Variables rooms, dist_centar, num_high, dist_gara, dist_otp were omitted for collinearity."
