The Exceptional Set

A statistical model, refit weekly across the in-stock catalog, estimates what a coffee with this exact profile typically sells for per ounce. Each multiplier compares one trait against the average lot in this market; the roaster line covers brand and sourcing together, which this model cannot separate. Bag size is shown separately, priced at the rate observed across sizes of the same coffee, because it says nothing about the coffee itself. The distribution counts every in-stock lot in the comparison class, so it moves as the catalog does. The model reads listed attributes only: the quality of the specific lot in the bag is not observable, so a price above the typical band is not evidence of overpricing.

Some listing details are missing, so the typical band shown is wider than usual.

Not listed by the roaster: origin, process, variety, roast level, altitude
