A method for evaluating the aggregate contributions of the different characteristics on the overall quality adjustment is developed in order to make the hedonic method more transparent in the context of classical index number theory. It is shown, that each step of the procedure has a very close analogue in the standard practice of statistical offices. A hedonic-method quality adjustment is performed within each cell in a classification and then the index is computed by aggregating cell level quality adjusted prices using an index number formula. To overcome the disadvantages of these methods the two approaches are combined. The feasible classification may be too rigid to capture relevant quality changes and the standard time-dummy hedonic approach is not easily interpretable in the context of traditional index number theory. Each method has proved to have drawbacks.
