Huff Model Calibration (Business Analyst)

Доступно с лицензией Business Analyst.

Сводка

Calculates exponent values for use in the Huff Model tool.

Использование

• 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.
