Interval constraints for the treatment of the partial data problem in gravity model calibration

R. Lebeuf and N. F. Stewart

Transportation Research Part B: Methodological, 1982, vol. 16, issue 3, 245-250

Abstract: The problem of indeterminacy, in the solution parameters of the Evans-Kirby calibration model, is discussed. A proposal is made to alleviate this problem, in the case of missing data, by introducing interval constraints.
