Sample size: text states 11,128 records (methods section also mentions selecting 500 as a sample, but the conclusion and F-statistic (F=1920.9, R2=0.464, 5 regressors) are consistent with n of about 11,100). Table 2 (p.3, six regressors) and Table 4 (p.4, five regressors) report unstandardised B with S.E., standardised Beta, t and p; ** denotes p<0.01 (legend not printed). 'District' (administrative district coded as a number) and 'CommunityID' (identifier) are not hedonic characteristics and are not extracted. BuldFloor = highest floor of the building (building height in storeys). No R2 printed for Table 2; Table 5 gives R2 0.464 for the Table 4 model."
