A Note on the Wald, Lagrangian Multiplier and Likelihood Ratio Tests when the Information Matrix is Singular [PDF]
The Egyptian Statistical Journal, 1988 Modified formulas for the Wald and Lagrangian multiplier statistics are introduced and considered together with the likelihood ratio statistic for testing a typical null hypothesis Ho stated in terms of equality constraints.

On a Constrained Testing Hypotheses Problem. [PDF]
The Egyptian Statistical Journal, 1997 This paper gives a proof that the likelihood ratio statistic, based on a sample x= (x1,…,xn) on a p-dimensional random variable X, converges in distribution to a noncentral chi-square distribution under a class of local alternatives, for a multi ...

Flexible scan statistic with a restricted likelihood ratio for optimized COVID-19 surveillance
Geospatial HealthDisease surveillance remains important for early detection of new COVID-19 variants. For this purpose, the World Health Organization (WHO) recommends integrating of COVID-19 surveillance with other respiratory diseases.

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1984 SUMMARY For rather general parametric models, a simple connection is established between the Bartlett adjustment factor of the log-likelihood ratio statistic and the normalizing constant c of the formula c | ĵ |½ L̄ for the conditional distribution of a maximum likelihood estimator as applied to the full model and the model of the ...

Empirical Likelihood for Partial Parameters in ARMA Models with Infinite Variance
Journal of Applied Mathematics, 2014 This paper proposes a profile empirical likelihood for the partial parameters in ARMA(p,q) models with infinite variance. We introduce a smoothed empirical log-likelihood ratio statistic. Also, the paper proves a nonparametric version of Wilks’s theorem.

Power Analysis for the Multivariable Logistic Model Using the Likelihood Ratio Test [PDF]
The Egyptian Statistical Journal, 2003 An asymptotic approach for conducting power analysis is described for the multiple logistic regression model. It is based on the likelihood ratio test statistic.

A measure of evidence based on the likelihood-ratio statistics [PDF]
Statistical Papers, 2022 In this paper, we show that the likelihood-ratio measure (a) is invariant with respect to dominating sigma-finite measures, (b) satisfies logical consequences which are not satisfied by standard $p$-values, (c) respects frequentist properties, i.e., the type I error can be properly controlled, and, under mild regularity conditions, (d) can be used as ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT We assessed the effect of iron overload (IO) on mortality and complications following hematopoietic stem cell transplantation (HSCT) in patients with Diamond–Blackfan anemia syndrome (DBAS) in a systematic review of individual participant data and cohort data from observational studies.
