Abstract This paper discusses theoretically the statistical tests and measures that are commonly used to evaluate the accuracy of the calibration of gravity models. It is shown that an inappropriate treatment of trip matrices as a certain type of contingency table has yielded erroneous interpretations. Also one of the most commonly used techniques in this context, the correlation coefficient, is inappropriate. Finally a further method of analysis involving the likelihood is proposed.
