The Wald test and Crame/spl acute/r-Rao bound for misspecified models in electromagnetic source analysis
2005
IEEE Transactions on Signal Processing
Preserved Fulltext
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. ...
