Abstract. The theoretical background of spatial interaction models is reviewed and used as a basis for the derivation of a novel approach for directly calibrating spatial interaction models concurrently with the main solution procedure. The analysis was prompted by a link with Fisher information. The new approach is compared with a number of earlier approaches, particularly that of Sen and Smith.
