Rao and Wald Tests for Nonhomogeneous Scenarios [PDF]
Sensors, 2012 In this paper, we focus on the design of adaptive receivers for nonhomogeneous scenarios. More precisely, at the design stage we assume a mismatch between the covariance matrix of the noise in the cell under test and that of secondary data.

Generalised Score and Wald Tests [PDF]
Advances in Decision Sciences, 2010 The generalised score and Wald tests are described and related to their nongeneralised versions. Two interesting applications are discussed. In the first a new test for the Behrens-Fisher problem is derived. The second is testing homogeneity of variances from multiple univariate normal populations.
