Bootstrap validity for the score test when instruments may be weak
(2009)
It is well-known that size adjustments based on bootstrapping the t-statistic perform poorly when instruments are weakly correlated with the endogenous explanatory variable. In this paper, we provide a theoretical proof ...
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 ...
On score tests in structural regression models
(GORDON BREACH SCI PUBL LTD, 1998)
In this paper we investigate the distribution of the score statistics for testing hypothesis about the slope parameter in a simple structural regression model. It is shown that for two of the most common ways of making the ...

Hypotheses Testing on a Multivariate Null Intercept Errors-in-Variables Model
(TAYLOR & FRANCIS INC, 2009)
Considering the Wald, score, and likelihood ratio asymptotic test statistics, we analyze a multivariate null intercept errors-in-variables regression model, where the explanatory and the response variables are subject to ...
Statistical Assessment Of Estimated Transformations In Observed-Score Equating
(2016)
Equating methods make use of an appropriate transformation function to map the scores of one test form into the scale of another so that scores are comparable and can be used interchangeably. The equating literature shows ...
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. ...
Comparação, em mulheres inférteis, de teste de avaliação psicológica com a análise psicanalítica clássica
(2004-01-01)
This study aims to compare a psychological evaluation test to classical psychoanalysis in infertile women. Two hundred women were submitted to the Psychological Evaluation Test (PET). The sum of the scores for the responses ...
