cafegetchisq

           compute chi^2 value for current parameters/data

           cafe

           show/fit

           param=cafegetchisq( env)

           env      - Environment containing parameters.
           selected - Compute Chi^2 for selected data points only

           Returns Chi^2, i.e. squared normalized deviation sum
           between data y values and model.
           chi^2 = sum((y_i - f(x_i))/err_i)

           none.

 Revision 1.8  2005/01/04 10:56:05  goehler
 fix: make shure all (internal) routines are properly documented
 Revision 1.7  2003/04/25 18:38:36  goehler
 safer estimation of chi^2 when error is zero
 Revision 1.6  2003/03/03 11:18:33  goehler
 major change: environment struct has become a pointer -> support of wplot/command line
 in common.
 Branch to be able to maintain the former line also.
 Revision 1.5  2002/09/10 13:24:35  goehler
 updated name convention:
 - the command name for all commands
 - the command name + "_" + subcommand name for all subcommands
 Revision 1.4  2002/09/10 13:06:47  goehler
 removed ";-" to make auxilliary routines invisible
 Revision 1.3  2002/09/09 17:36:19  goehler
 public version: updated help matching aitlib html structure.
 common version: 3.0
