Abstract
The G index of agreement does not permit the use of various weights for its various items. The weighted G index described here, makes it possible to use unequal weights. The weighted G index satisfies the requirements of a scalar product between normalized vectors, and a Q component analysis may, therefore, be based on it. It is also invariant over item reflection.Keywords
