Eight hedonic factors. For each one the page shows return (how the market re-priced the characteristic), composition (how the basket of sold properties shifted), beta (the OLS coefficient path with p-value), and distribution (what has actually been transacted).
Rolling 3-month cross-sectional OLS on log(price/sqm), 1995 to present. Full methodology on the About page.
Cumulative intercept drift, compositional shifts and control-dummy contributions. Everything not attributed to a tracked factor ends up here.
Pure market repricing: how much each characteristic changed in valuation terms.
A factor can have a flat return while its composition (β·ΔX) still moved. That drift is folded into Baseline above.
For each factor j, the period-on-period change in the quality-adjusted log-price is split as Δŷ = Δα + Σj [βt·ΔXj + Xt·Δβj − Δβj·ΔXj]. We report Xt·Δβj as the factor return, βt·ΔXj as the composition (bundled into Baseline), and the cross term as an explicit reconciliation column.
