grocery2: Grocery store market areas in Goettingen

Description

Market areas of grocery stores in Goettingen, generated from a POS survey in Goettingen (Germany) from June 2015. The survey dataset contains 224 cases ($i$ = 7 submarkets x $j$ = 32 suppliers). The data is the result of a survey that is not representative (see grocery1) and also biased due to the data preparation. The data should be regarded as an example.
