Hermite and Laguerre Symmetric Functions Associated with Operators of Calogero-Moser-Sutherland Type
(NATL ACAD SCI UKRAINE, INST MAT, 2012)
Transformed symmetric models
(SAGE PUBLICATIONS LTD, 2011)
For the first time, we introduce a class of transformed symmetric models to extend the Box and Cox models to more general symmetric models. The new class of models includes all symmetric continuous distributions with a ...
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. ...
Estudo sobre os modelos não-lineares simétricos: aspectos inferenciais e aplicações
(Universidade Federal do Rio Grande do NorteBrasilUFRNEstatística, 2018-12-13)
Outliers appear in the analyses of various datasets, which can affect the parameter estimation by distorting the point estimations, for instance. One way to deal with datasets that have outliers is to suppose a distribution ...
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 ...
Fisher information and α-connections for a class of transformational models
(2000)
In this paper we use invariant theory for representations of groups in order to get an indirect method of computing the Fisher metric and the α-connections of transformational models parameterized by symmetric spaces. Among ...
