The Laplace Likelihood Ratio Test for Heteroscedasticity [PDF]

International Journal of Mathematics and Mathematical Sciences, 2011
It is shown that the likelihood ratio test for heteroscedasticity, assuming the Laplace distribution, gives good results for Gaussian and fat-tailed data.

Real time QRS detection based on M-ary likelihood ratio test on the DFT coefficients. [PDF]

PLoS ONE, 2014
This paper shows an adaptive statistical test for QRS detection of electrocardiography (ECG) signals. The method is based on a M-ary generalized likelihood ratio test (LRT) defined over a multiple observation window in the Fourier domain. The motivations

New Forms of Likelihood Ratio Test for SAR Change Detection

IEEE Access, 2021
The Neyman-Pearson lemma, i.e., the likelihood ratio test and its generalized version, have been used for the development of the synthetic aperture radar (SAR) change detection methods.

A likelihood ratio test for nested proportions. [PDF]

Stat Med, 2015
For policy and medical issues, it is important to know if the proportion of an event changes after an intervention is administered. When the later proportion can only be calculated in a portion of the sample used to compute the previous proportion, the two proportions are nested.

X-Gamma Lomax Distribution with Different Applications [PDF]

مجلة العلوم التجارية والبيئية, 2022
The X-Gamma Lomax (XGLo) distribution, a new three-parameter modification of the Lomax distribution, was introduced and examined in this study. This distribution's features for reliability and hazard rate are addressed.

Distributed Intermittent Fault Diagnosis in Wireless Sensor Network Using Likelihood Ratio Test

IEEE Access, 2023
In current days, sensor nodes are deployed in hostile environments for various military and commercial applications. Sensor nodes are becoming faulty and having adverse effects in the network if they are not diagnosed and inform the fault status to other

Target Maneuver Detection Method Based on Likelihood Ratio Test [PDF]

Hangkong bingqi
Aiming at the target maneuver detection in antagonistic process, a detection method is proposed based on likelihood ratio test. Based on the target real time observation data, the target detection problem is translated into the problem of time series ...
