摘要
Calculates exponent values for use in the Huff Model tool.
使用情况
The output exponents are based on attractiveness values of the existing facilities and their spatial relationship to customer points.
Customer point data is a required input.
The Huff Model Calibration output is stored in the Business Analyst container in the Catalog pane.
Exponent values are correlated to the market defined by the inputs. Although they can be applied to additional markets, they may be less reliable in those scenarios.
The Huff Model Calibration output can be applied to the Huff Model tool.
