A new robust and most powerful test in the presence of local misspecification
(Taylor & Francis, 2017-08)
This article proposes a new test that is consistent, achieves correct asymptotic size, and is locally most powerful under local misspecification, and when any √n-estimator of the nuisance parameters is used. The new test ...
Improved score tests in symmetric linear regression models
(TAYLOR & FRANCIS INC, 2008)
The class of symmetric linear regression models has the normal linear regression model as a special case and includes several models that assume that the errors follow a symmetric distribution with longer-than-normal tails. ...
Higher-order asymptotic refinements for score tests in proper dispersion models
(2001)
This paper develops second-order asymptotic theory for score tests in proper dispersion models without imposing known dispersion. Our results can be used to provide an Edgeworth expansion for the test statistic or to obtain ...
Score test para el efecto del coeficiente de solapamiento en modelos de superficies de respuesta de primer y segundo orden
(Universidad Nacional de Colombia Sede Medellín, 2011)
En este artículo ha sido propuesto un test para el coeficiente de solapamiento para el modelo de Draper y Guttman utilizando modelos de superficies de respuesta de primer y segundo orden. El test está basado en el test de ...
Effect of dulaglutide on cognitive impairment in type 2 diabetes: an exploratory analysis of the REWIND trial
(ElsevierReino Unido, 2020-07-01)
Background
Diabetes is an independent risk factor for cognitive impairment. We aimed to investigate the association between the glucagon-like peptide-1 (GLP-1) receptor agonist dulaglutide and cognitive impairment as an ...

(2019)
Latent variables used in Item Response Theory (IRT) models are specified by the axiom of local independence (ALI). By doing this, latent variables explain the non random variations in the observed scores, thus, latent ...
Una revisión de medidas multivariadas de asimetría y kurtosis para pruebas de multinormalidad
(Universidad Nacional de Colombia, 1999)
El trabajo germinal de Mardia(1970) da definiciones multivariadas de asimetría y kurtosis que son usadas en pruebas de multinormalidad, y han dado origen a gran variedad de extensiones y formalizaciones. Se hace una revisión ...
Modelos série de potência com excesso de zeros observáveis e latentes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Estatística - PPGEsCâmpus São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable
and latent data. In observable data set that occur excess of zeros, its common to have
sobredispersion. In this sense, the models ...
