The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The huff Python package provides a complete workflow for market area analysis, including data import, construction of origin-destination interaction matrices, basic model analysis, parameter estimation from empirical data, calculation of distance or travel time indicators, and map visualization.

C2weakest assumption

That the package correctly implements the Huff model and extensions without bugs and that users' data satisfy the model's assumptions for parameter estimation.

C3one line summary

The huff package supplies a modular Python workflow for market area modeling, data handling, parameter fitting, and accessibility analysis using the Huff model and extensions.
