Since coarse(ned) data naturally induce set-valued estimators, analysts often assume coarsening at random (CAR) to force them to be single-valued. Focusing on a coarse categorical response variable and a precisely observed categorical covariate, we re-illustrate the impossibility to test CAR and contrast it to another type of coarsening called subgroup independence (SI), using the data of the G...

in this investigation, the effect of group cognitive-behavior therapy in reduction of anxiety and dysfunctional attitude were studied on patients with generalized anxiety disorder (gad). 20 female participants were recognized to have gad by the researcher through a clinical interview on the basis of dsm-iv-tr standards and invited to take part in the study. they first filled in the dysfunctiona...

dividend policy is one of the most important financial decisions that managers encounter. this study contributes to the literature of dividend and empirical research investigating the effects of dynamic factors in tehran stock exchange. based on some criteria, the study contains 133 listed firms over a 10-year period from 2001 to 2010. to test the research hypotheses, this study uses fixed effe...

We study a class of infinite dimensional Lie algebras called generalized Witt algebras (in one variable). These include the classical Witt algebra and the centerless Virasoro algebra as important examples. We show that any such generalized Witt algebra is a semisimple, indecomposable Lie algebra which does not contain any abelian Lie subalgebras of dimension greater than one. We develop an inva...

Abstract: This paper develops some objective priors for certain parameters of the bivariate normal distribution. The parameters considered are the regression coefficient, the generalized variance, and the ratio of the conditional variance of one variable given the other to the marginal variance of the other variable. The criterion used is the asymptotic matching of coverage probabilities of Bay...

This paper introduces a class of linear phase lapped biorthogonal transforms with basis functions of variable length (VLGLBT). The transform can be characterized by a lattice which structurally enforces both linear phase and perfect reconstruction properties as well as provides a fast and e cient transform implementation. Our main motivation of the new transform is its application in image codi...
