Likelihood Ratio Test

Eserciziario di Statistica Inferenziale, 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 ...

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.

Generalized Likelihood Ratio Test for GNSS Spoofing Detection in Devices With IMU

IEEE Transactions on Information Forensics and Security, 2021
Spoofing attacks in global navigation satellite systems (GNSSs) aim at inducing the estimation of a fake position at the victim receiver. Many devices, including smartphones, are nowadays equipped with both a GNSS receiver and an inertial measurement ...

One-Step Generalized Likelihood Ratio Test for Subpixel Target Detection in Hyperspectral Imaging

IEEE Transactions on Geoscience and Remote Sensing, 2020
One of the main objectives of hyperspectral image processing is to detect a given target among an unknown background. The standard data to conduct such detection is a reflectance map, where the spectral signatures of each pixel’s components, known as ...

Adaptive Generalized Likelihood Ratio Test for Change Detection in SAR Images

IEEE Geoscience and Remote Sensing Letters, 2020
Generalized likelihood ratio test (GLRT) was widely used in the change detection of synthetic aperture radar (SAR) images and employed as a competitive method in many studies.

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 \(r(y;\theta,\lambda)\).

Generalized Likelihood Ratio Test Based Approach for Stator-Fault Detection in a PWM Inverter-Fed Induction Motor Drive

IEEE transactions on industrial electronics (1982. Print), 2019
This paper proposes a new approach for the detection of stator faults in inverter-fed induction motor under closed-loop control. These faults, generally, start with interturn short circuit and can evolve to phase-to-phase or phase-to-ground faults ...

The likelihood ratio test in high-dimensional logistic regression is asymptotically a rescaled Chi-square

Probability theory and related fields, 2017
Logistic regression is used thousands of times a day to fit data, predict future outcomes, and assess the statistical significance of explanatory variables.

Paternity testing. 2: Likelihood ratio tests

American Journal of Medical Genetics, 1985
AbstractIt is known that the so‐called paternity index is also a likelihood ratio statistic for testing that an alleged father is the true father. Unfortunately the likelihood ratio test can sometimes lead to unsatisfactory results because of its dependence on the phenotype combinations of the mother and child. A new, conditional likelihood ratio test,
