Deviance values Eq. (8) for radiation models A, B, C, E, F, G, H (from left to right) described in Table 1, alongside the production constrained gravity model of Eq. (2), with data sets that are truncated using the minimum values shown in the legend. Lower values represent better models. These data are from the US Census 20001. For each model the top of a coloured bar represents the deviance value for that model when the data is limited to flows above the value indicated in the legend.
