We characterize the conditions under which weighted norm inequalities for a positive operator T can be obtained by interpolation with change of measure. The results are applied to the construction of all good weight pairs for T . This construction is used to show that the study of weighted norm inequalities for operators T that factor as T = PQ reduce to that of the weighted norm inequalities for the factors P and Q .
