Price Trends

Every point is one listing from the DriversHub listings index. In One per listing mode the point is the initial asking priceat the date the listing first appeared; the event modes plot every recorded price change. Trend lines are robust locally-weighted regressions (LOWESS with a k-nearest-neighbor span and outlier rejection) fitted in your browser; legend drift figures compare fitted values at the 10th and 90th percentile of each band's window, and annualized rates are shown only for spans of a year or more. When a search matches more than Max points, the newest listings are kept and the metrics say so. Results are cached locally for 30 minutes.
