Utilidad de los scores de Glasgow y score ABIC como predictores de muerte en pacientes adultos con cirrosis hepática alcohólica descompensada
(Universidad Privada Antenor Orrego - UPAO, 2019)
Latent variables should remain as such: Evidence from a Monte Carlo study
(Routledge, 2019)
Use of subject scores as manifest variables to assess the relationship between latent variables produces attenuated estimates. This has been demonstrated for raw scores from classical test theory (CTT) and factor scores ...
Three Bartlett-type corrections for score statistics in symmetric nonlinear regression models
(SPRINGER, 2010)
We present simple matrix formulae for corrected score statistics in symmetric nonlinear regression models. The corrected score statistics follow more closely a chi (2) distribution than the classical score statistic. Our ...
Local power of some tests in exponential family nonlinear models
(ELSEVIER SCIENCE BV, 2011)
In this paper we obtain asymptotic expansions up to order n(-1/2) for the nonnull distribution functions of the likelihood ratio, Wald, score and gradient test statistics in exponential family nonlinear models (Cordeiro ...
Size and power properties of some tests in the Birnbaum-Saunders regression model
(ELSEVIER SCIENCE BV, 2011)
The Birnbaum-Saunders distribution has been used quite effectively to model times to failure for materials subject to fatigue and for modeling lifetime data. In this paper we obtain asymptotic expansions, up to order n(-1/2) ...
Local power properties of some asymptotic tests in symmetric linear regression models
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper we obtain asymptotic expansions, up to order n(-1/2) and under a sequence of Pitman alternatives, for the nonnull distribution functions of the likelihood ratio, Wald, score and gradient test statistics in ...
The Correlation Between Students’ Progress Testing Scores and Their Performance in a Residency Selection Process
(2019-12-01)
Brazil is currently seeing an increased number of medical schools, leading to high competition for medical residency vacancies. Public managers have thus considered Progress Testing scores potentially useful as part of the ...
Closed Kinetic Chain Upper Extremity Stability test (CKCUES test): a reliability study in persons with and without shoulder impingement syndrome
(Biomed Central Ltd, 2014-01-03)
Background: the Close Kinetic Chain Upper Extremity Stability Test (CKCUES test) is a low cost shoulder functional test that could be considered as a complementary and objective clinical outcome for shoulder performance ...
The local power of the gradient test
(SPRINGER HEIDELBERGHEIDELBERG, 2012)
The asymptotic expansion of the distribution of the gradient test statistic is derived for a composite hypothesis under a sequence of Pitman alternative hypotheses converging to the null hypothesis at rate n(-1/2), n being ...
