Quote from FED:

>The hedonic quality adjustment method removes any price differential attributed to a change in quality by adding or subtracting the estimated value of that change from the price of the old item.

What do you think "attributing a change in quality" or subtracting "estimated value" means? If you don't understand how the introduction of these arbitrary variables, invented by a politicized FED, completely nullify any informational value, nobody can explain it to you.
