  "notes": "Paper is about house price index construction; only Table 2 prints attribute coefficients. CAUTION: Table 2 reports the AVERAGE of four urban-level hedonic imputation (HI) model betas estimated for Alicante province in 2010 (4 quarters), with standardized betas and an (averaged) 'Stand. error' column; it is not a single regression column. Printed N = 596,170 although the note says 478,418 usable Alicante observations overall and ~11,390 per quarter of 2010. Dependent variable = log of asking prices (semi-log; m2 and population enter in logs). Variable definitions are in supplementary Table S1 (not in the PDF); most neighbourhood/city variables are valuer-perception categorical ratings, so units are unknown. Stars: *** p<0.001, ** p<0.01, * p<0.05. All coefficients recorded with confidence 'medium' because of the averaging; standardized betas are not extracted."
