Question

Is an example available for the Procedure "Estimate gravitation parameters (KALIBRI)"?

Answer

See the attached example file.

This demonstrates the necessary steps:
- Assignment
- Skim matrix calculation
- Create a histogram, classify to obtain the shares per interval. (Demand = matrix 25, classification matrix = matrix 26)
- Save from the histogram the intervals for Kalibri: Matrix histogram -> Save intervals. Note: Share = 0 for the first and the last interval.
- Setup the Procedure "Estimate gravitation parameters (KALIBRI)": Tab "Distribution" -> Read from file (use the saved intervals)
This example estimates the parameter c for the Demand stratum "HW_Emp", stored in an respective attribute.
