Whole‐Body Pattern of Muscle Degeneration and Progression in Sarcoglycanopathies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterize whole‐body intramuscular fat distribution pattern in patients with sarcoglycanopathies and explore correlations with disease severity, duration and age at onset. Methods Retrospective, cross‐sectional, multicentric study enrolling patients with variants in one of the four sarcoglycan genes who underwent whole‐body ...

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

Likelihood Ratio Specification Tests

Econometrica, 1997
Summary: Misspecification tests for parametric models, \(f(y,\theta)\), that examine data for failure of moment conditions implied by the maintained parametric distribution are interpreted as score tests of \(H_0:\lambda=0\) in the context of a parametric family of distributions \(r(y;\theta,\lambda)\).

Likelihood-ratio detection

Proceedings of 1994 IEEE International Symposium on Information Theory, 2002
The composite hypothesis test for the case of unknown distribution for an unknown parameter is considered, and it is shown that the optimum test is the average likelihood ratio test with uniform f/sub /spl theta//; it is equivalent to the uniformly most powerful (UMP) test, if there is a UMP test for the problem, and it performs essentially better than

Likelihood Ratio Test

2020
In questo capitolo vengono proposti esercizi sulla teoria della verifica delle ipotesi (test d’ipotesi) a partire da un modello di campionamento casuale parametrico, in particolare: livello di un test d’ipotesi; errore di I tipo ed errore di II tipo; funzione potenza di un test d’ipotesi; costruzione di test d’ipotesi basati sulla statistica del ...

Repeated likelihood ratio tests

Biometrika, 1979
SUMMARY We study the actual significance level which results from performing repeated likelihood ratio tests over time. We present a general method for estimating the actual significance level when sampling from an exponential family, and apply it to problems of testing hypotheses about means, variance, correlations and failure rates.

Likelihood Ratio Test

2015
In the previous chapter, we have seen that UMP or UMP-unbiased tests exist only for some special families of distributions, while they do not exist for other families.

Clinical Utility of Likelihood Ratios

Annals of Emergency Medicine, 1998
Test-performance characteristics can be derived from a simple 2x2 table displaying the dichotomous relationship between a positive or negative test result and the presence or absence of a target disorder. Sensitivity and specificity, including a summary display of their reciprocal relationship as a receiver operating characteristics curve, are ...
