  1. The table shows the performance of the hybrid models in terms of the Pearson correlation coefficient ρ and the determination coefficient \(\mathrm{r}^{2}\). We also display the results for the gravity model, the radiation model and the Flickr model alone. All the values were produced under a 10-fold cross-validation scheme, except for the radiation model (as noted by the asterisk), which is parameter free.
