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.

Colonial competitive evolutionary Rao algorithm for optimal engineering design

AEJ - Alexandria Engineering Journal, 2022
Rao algorithms that include three algorithms are very simple and parameter-less algorithms with effective and desirable performance. This paper modifies these three algorithms, merges them, and establishes a powerful group algorithm.

Generalised RAO test for polarimetric target detection

The Journal of Engineering, 2019
Here, a generalised Rao test method is presented for polarimetric multichannel adaptive signal detection. By introducing several tunable parameters into the Rao test detection statistics, the proposed polarimetric detector is quite general with the ...

A Robust Generalization of the Rao Test [PDF]

Journal of Business & Economic Statistics, 2021
This article presents new families of Rao-type test statistics based on the minimum density power divergence estimators which provide robust generalizations for testing simple and composite null hypotheses. The asymptotic null distributions of the proposed tests are obtained and their robustness properties are also theoretically studied.

Distributional Censored and Uncensored Validation Testing under a Modified Test Statistic with Risk Analysis and Assessment

Journal of Mathematics, 2023
This paper introduces and studies a unique probability distribution. The maximum likelihood estimation, the ordinary least squares, the weighted least squares, and the Anderson–Darling estimation methods all take into account a number of financial risk ...

Passive MIMO radar detection in the presence of clutter or multi‐path without reference channel

IET Radar, Sonar & Navigation, 2021
Target detection problem in a multiple‐input multiple‐output (MIMO) radar which includes non‐cooperative illuminators of opportunity (IOs) and spatially distributed receivers is discussed. The receivers utilize only one processing channel and discard the
