A likelihood ratio test for changes in homeolog expression bias [PDF]
BMC Bioinformatics, 2019 Background Gene duplications are a major source of raw material for evolution and a likely contributor to the diversity of life on earth. Duplicate genes (i.e., homeologs, in the case of a whole genome duplication) may retain their ancestral function ...

The Geometry of Generalized Likelihood Ratio Test [PDF]
Entropy, 2022 The generalized likelihood ratio test (GLRT) for composite hypothesis testing problems is studied from a geometric perspective. An information-geometrical interpretation of the GLRT is proposed based on the geometry of curved exponential families.

Cancelable ECG Biometrics Using Compressive Sensing-Generalized Likelihood Ratio Test
IEEE Access, 2019 Electrocardiogram (ECG) has been investigated as promising biometrics, but it cannot be canceled and re-used once compromised just like other biometrics.

Robust DFT‐based generalised likelihood ratio test for underwater tone detection
IET Radar, Sonar & Navigation, 2017 The discrete Fourier transform (DFT) of observation sequence is usually used in the detection of tonal signal. A tone without any prior information cannot be guaranteed to lie exactly on the discrete DFT frequency bin, which will degrade the performance ...

Likelihood Ratio Test and the Evidential Approach for 2 × 2 Tables [PDF]
EntropyCategorical data analysis of 2 × 2 contingency tables is extremely common, not least because they provide risk difference, risk ratio, odds ratio, and log odds statistics in medical research.

Restricted likelihood ratio testing in linear mixed models with general error covariance structure [PDF]
, 2011 We consider the problem of testing for zero variance components in linear mixed models with correlated or heteroscedastic errors. In the case of independent and identically distributed errors, a valid test exists, which is based on the exact finite ...

Likelihood Ratio Test for Excess Homozygosity at Marker Loci on X Chromosome. [PDF]
PLoS ONE, 2015 The assumption of Hardy-Weinberg equilibrium (HWE) is generally required for association analysis using case-control design on autosomes; otherwise, the size may be inflated.
