  "notes": "Price is owner-reported house value from interviews (not transaction); coded 'appraisal' (owner estimate). Four Box-Cox maximum-likelihood models (Table 5, p.9): lhsonly (theta=0.476 on price only), rhsonly (lambda=-0.178 on regressors only), lambda (common 0.175), theta (theta=0.288, lambda=-0.461; preferred by AIC/BIC). Values in parentheses under coefficients are NOT standard errors or t-statistics: they are the chi-square(1) test statistics of Stata's boxcox output (e.g. Detach 434.886*** (26.884); Age -0.398 (0.033)); recorded in notes, se/t left null. Stars: * p<0.10, ** p<0.05, *** p<0.01 (inferred legend; legend not printed - treat as medium confidence). Air pollution (AQI) has only two values (two monitoring stations). Detached (1) vs townhouse (0) dummy. Continuous regressors Box-Cox transformed in rhsonly/lambda/theta models (which variables transformed not fully explicit; Eq. 10 lists Bath, Lot, AQI). Implicit prices (Table 6, p.10, theta model): Detach THB 299,259; Bath THB 6,593; Lot THB 2,221/m2; AQI -THB 2,815 per unit."
