   *********************Model calibration information*********************
   Kernel function for geographically and temporally weighting: gaussian 
   Adaptive bandwidth for geographically and temporally  weighting: 20 (number of nearest neighbours)
   Regression points: A seperate set of regression points is used.
   Distance metric for geographically and temporally  weighting: A distance matrix is specified for this model calibration.
