SPatial INTeraction models
Spatial Interaction Modeling Package
The Spatial Interaction Modeling SpInt module seeks to provide a collection of tools to study spatial interaction processes and analyze spatial interaction data.
The module currently supports the calibration of the ‘family’ of spatial interaction models Wilson, 1971 which are derived using an entropy maximizing EM framework or the equivalent information minimizing IM framework. As such, it is able to derive parameters for the following Poisson count models
- unconstrained gravity model
- production-constrained model origin-constrained
- attraction-constrained model destination-constrained
- doubly-constrained model
