Stepwise Likelihood Ratio Statistics in Sequential Studies

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2004
SummaryIt is well known that in a sequential study the probability that the likelihood ratio for a simple alternative hypothesis H1versus a simple null hypothesis H0 will ever be greater than a positive constant c will not exceed 1/c under H0. However, for a composite alternative hypothesis, this bound of 1/c will no longer hold when a generalized ...

Change Detection in Multilook Polarimetric SAR Imagery With Determinant Ratio Test Statistic [PDF]

open access: yes, 2022
In this article, we propose a determinant ratio test (DRT) statistic to measure the similarity of two covariance matrices for unsupervised change detection in polarimetric radar images.

The asymptotic local structure of the Cox modified likelihood-ratio statistic for testing non-nested hypotheses [PDF]

open access: yes, 1992
It is shown that the Cox modified likelihood-ratio statistic for testing partially non-nested hypotheses H0 and H1 is asymptotically equivalent to a bilinear form in nondegenerate asymptotically normal random vectors for sequences of data-generating ...

Restricted Likelihood Ratio Testing in Linear Mixed Models with General Error Covariance Structure [PDF]

open access: yes, 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 ...

Some Restricted Estimation and Testing Hypotheses Problem With Singularity Assumption [PDF]

open access: yesThe Egyptian Statistical Journal, 1994
The limiting distribution of the likelihood ratio statistic (LR) under a class of local alternatives as developed earlier by Davidson and Lever, is extended to the case of singular information matrices.

Test of fit for Cauchy distribution based on the empirical likelihood ratio with application to the stock market price [PDF]

open access: yesJournal of Mahani Mathematical Research, 2022
Recently, it has been shown that the density based empirical likelihood concept extends and standardizes these methods, presenting a powerful approach for approximating optimal parametric likelihood ratio test statistics.

Generalized Correlation Coefficient Based on Log Likelihood Ratio Test Statistic

open access: yesMATEC Web of Conferences, 2016
In this paper, I point out that both Joe’s and Ding’s strength statistics can only be used for testing the pair-wise independence, and I propose a novel G-square based strength statistic, called Liu’s generalized correlation coefficient, it can be used ...
