The data area is used for the storage of data, including dummy variables, and is used by the model fitting routines for inverting matrices. Alter the size of X in the main program in file sabre.f to the required value. Change the size of the array ORD in the main program in file sabre.f to be of size MAXY . To change the maximum number of variables to a larger value is more complicated. It involves making the above changes, and also changing the dimensions of certain other arrays in other subroutines.
Further details are available from the authors on request.
The size of the parameter storage area and the maximum number of parameters The parameter storage area is used for the storage of the current parameter estimates, the variance-covariance matrix and the aliasing indicators and is used in the model fitting for calculating numerical derivatives. To change the maximum number of parameters to a larger value is more complicated. It involves making the above changes, and also changing the dimensions of certain other arrays in other subroutines. Further details are available from the authors on request. This is not usually necessary, but may be required at certain installations.
