The Geometry of Generalized Likelihood Ratio Test [PDF]

open access: yesEntropy, 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.

Computer assisted diagnosis of Alzheimer's disease using statistical likelihood-ratio test. [PDF]

open access: yesPLoS ONE, 2023
The purpose of this work is to present a computer assisted diagnostic tool for radiologists in their diagnosis of Alzheimer's disease. A statistical likelihood-ratio procedure from signal detection theory was implemented in the detection of Alzheimer's ...

The Laplace Likelihood Ratio Test for Heteroscedasticity [PDF]

open access: yesInternational 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.

A likelihood ratio test for changes in homeolog expression bias [PDF]

open access: yesBMC 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 ...

A likelihood ratio test for the homogeneity of between-study variance in network meta-analysis [PDF]

open access: yesSystematic Reviews, 2021
Background Network meta-analysis (NMA) is a statistical method used to combine results from several clinical trials and simultaneously compare multiple treatments using direct and indirect evidence.

Likelihood Ratio Test and the Evidential Approach for 2 × 2 Tables [PDF]

open access: yesEntropy
Categorical 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.

Likelihood-ratio test statistic for the finite-sample case in nonlinear ordinary differential equation models. [PDF]

open access: yesPLoS Computational Biology, 2023
Likelihood ratios are frequently utilized as basis for statistical tests, for model selection criteria and for assessing parameter and prediction uncertainties, e.g. using the profile likelihood. However, translating these likelihood ratios into p-values

A likelihood ratio test for nested proportions. [PDF]

open access: yesStat 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.

Likelihood Ratio Test for Excess Homozygosity at Marker Loci on X Chromosome. [PDF]

open access: yesPLoS 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.
