Two different, previously suggested Wald tests in electromagnetic source analysis (EMSA) are examined: a test on source amplitudes and a test on the closeness of source pairs. ... An accurate estimate of the Cramér-Rao bound (CRB) is required for the use of the Wald test when not all assumptions are satisfied. The sandwich CRB is used for this purpose. ... A prerequisite for using the Wald test in the way described above is that a good estimate of the Cramér-Rao bound (CRB) of the parameters is available, even for approximate models. ...doi:10.1109/tsp.2005.853213 fatcat:qwd56qj5v5favj7ovjteuc7nsi
