Testing hypothesis on degree distribution in the market graph
Current approaches to testing hypotheses on degree distribution of the market graph and of identifying power law in data are discussed, main drawbacks of these approaches are identified and ways to overcome them are provided. Brief summary on methodology used is given and main aspects are highlighted. Discussed methodology is applied to testing hypotheses on degree distribution of multiple market graphs and results obtained are presented. It is shown that more stable market research techniques question presence of power law in degree distribution.
