This vignette provides a description of the performance of each model in nomad and the mobility data that underpins those models. This vignette provides all the information required to help you identify the most suitable model for your needs.

Mobility Data

The following table provides the description and overall summaries of the different mobility data sets that have been used to create the mobility models stored in nomad. Users may wish to search for the data that they believe would be most representative for their use cases, e.g. collected from the same country, or collected at the same spatial scale.

Sample scheme details, censoring as well as the timing of the sample can all be viewed below.

To help identify which mobility data may be most suitable for your use case, we have provided the following interactive map to show you the locations of all available mobility data:

Model Performance

The following table provides the description and overall evaluation statistics of each model that is stored in nomad.

You can search across all the models, e.g. by searching for models that used the mobility data that you have identified as most suitable for your setting, or by sorting the model table with respect to desired model characteristics, e.g. lowest DIC. By default the table is sorted by the \(R^2\) of the model fit.

Alternatively, you could select for specific mobility models (gravity, radiation, and departure-diffusion) or their sub types (see ?mobility::mobility) for more information on sub-types.

Model Fit Checks

The overall summary statistics provided above may not be the most useful way to evaluate the model’s overall fit. Alternatively, you can view the model fit summary plots below by selecting for the given plot name:
