Table 2. Agreements between the travel fluxes predicted by the generalized radiation model and the travel fluxes observed in the real data.

We conduct the two-sample Kolmogorov-Smirnov test to verify whether the distributions of the model and the data are from an identical distribution at the 5% significance level in terms of overall travel distance distribution and travels towards (or from) given population. Values in red indicates non-agreements between the model prediction and the real data.
