huff: Huff Model Market Area Analysis

huff: Huff Model Market Area Analysis

This Python library is designed for performing market area analyses with the Huff Model (Huff 1962, 1964) and/or the Multiplicative Competitive Interaction (MCI) Model (Nakanishi and Cooper 1974, 1982). Users may load point shapefiles (or CSV, XLSX) of customer origins and supply locations and conduct a market area analysis step by step. The library supports parameter estimation based on empirical customer data using the MCI model and Maximum Likelihood. The package also includes supplementary GIS functions, including clients for OpenRouteService(1) for network analysis (e.g., transport cost matrix) and OpenStreetMap(2) for simple maps. See Huff and McCallum (2008) or Wieland (2017) for a description of the models and their practical application.
