A random effects probit model is developed for the case in which the same units are sampled repeatedly at each level of an independent variable. Because the observed proportions may be correlated under these conditions, estimating their trend with respect to the independent variable is no longer a standard problem for probit, logit or loglinear analysis. Using a qualitative analogue of a random regressions model, we employ instead marginal maximum likelihood to estimate the average latent trend line. Likelihood ratio tests of the hypothesis of no trend in the average line, and the hypothesis of no differences in average trend lines between experimental treatments, are proposed. We illustrate the model both with simulated data and with observed data from a clinical experiment in which psychiatric patients on two drug therapies are rated on five occasions for the presence or absence of symptoms.Supported by a grant from the MacArthur Foundation and National Science Foundation Grant BNS85-11774.The authors are indebted to James Heckman for calling our attention to the Clark algorithm. 相似文献

Psychometricians working in factor analysis and econometricians working in regression with measurement error in all variables are both interested in the rank of dispersion matrices under variation of the diagonal elements. Psychometricians concentrate on cases in which low rank can be attained, preferably rank one, the Spearman case. Econometricians cocentrate on cases in which the rank cannot be reduced below the number of variables minus one, the Frisch case. In this paper we give an extensive historial discussion of both fields, we prove the two key results in a more satisfactory and uniform way, we point out various small errors and misunderstandings, and we present a methodological comparison of factor analysis and regression on the basis of our results.Financial support by the Netherlands Organization for the Advancement of Pure Research (ZWO) is gratefully acknowledged. 相似文献

Simple tableau algorithms are given for the noniterative instrumental variable (FABIN 2) and two stage regression (FABIN 3) factor loading estimates of Hägglund. Corresponding generalized least squares estimates of factor covariances and unique variances are introduced. An example is given for the purpose of illustration and comparison.This research was supported by NSF Grant MCS-8301587. 相似文献

Kroonenberg and de Leeuw (1980) have developed an alternating least-squares method TUCKALS-3 as a solution for Tucker's three-way principal components model. The present paper offers some additional features of their method. Starting from a reanalysis of Tucker's problem in terms of a rank-constrained regression problem, it is shown that the fitted sum of squares in TUCKALS-3 can be partitioned according to elements of each mode of the three-way data matrix. An upper bound to the total fitted sum of squares is derived. Finally, a special case of TUCKALS-3 is related to the Carroll/Harshman CANDECOMP/PARAFAC model. 相似文献

In the course of the medical program at the University of Limburg, students complete a total of 24 progress tests, consisting of items drawn from a constant itembank. A model is presented for the growth of knowledge reflected by these results. The Rasch model is used as a starting point, but both ability and difficulty parameters are taken to be random, and moreover the logistic distribution is replaced by the normal. Both individual and group abilities are estimated and explained through simple linear regression. Application to real data shows that the model fits very well. 相似文献

‘I’m like the man who took along a brick/to show the world what his house was like.’ Reflecting on Bertolt Brecht’s brick, which is symbolically taken along from the homeland, allows us the opportunity to explore the changing modalities of traumatic experience in displaced persons. The brick does not merely represent lost objects, home, and homeland but also stands for the displaced person and his psychic integrity. The challenge for every displaced person is to transition away from the basic survival mode, dominated by the drives of self-preservation, to regain the ability to symbolize and to start dreaming again. The way a poet processes his own traumatic experiences of displacement and escape may serve as a roadmap for others. Works by Mario Benedetti and Bertolt Brecht, both émigré poets, alongside clinical examples, form the psychological material. Recurring thoughts of an uncertain return to the homeland may become debilitating, causing a displaced person to descend into mourning or melancholy and can even lead to open outbursts of previously strongly defended aggression. If it is not possible to sufficiently work through the trauma, then the bricks will fall everywhere. In the regressive emotionally charged condition, it holds true: in the beginning was the act. 相似文献

The main goal of this research was to examine how readers of Russian assign stress to disyllabic words. In particular, we tested the claim that the process of stress assignment in Russian can only be accomplished lexically. Eleven potential non-lexical sources of evidence for stress in Russian were examined in regression and factorial studies. In Study 1, onset complexity, coda complexity, the orthography of the first syllable (CVC1), of the second syllable (CVC2), and of the ending of the second syllable (VC2) were found to be probabilistically associated with stress in Russian disyllables. In Studies 2 and 3, it was shown that Russian speakers do use 3 of these cues (CVC1, CVC2, and VC2) when making stress-assignment decisions. These results provide evidence against the idea that the nature of stress in the Russian language is so unpredictable that stress assignment can only be accomplished lexically. These results also suggest that any successful model of stress assignment in Russian needs to contain mechanisms allowing these 3 orthographic cues to play a role in the stress-assignment process. 相似文献

This article defines healthy oneness experience and establishes the progressive, life enhancing components of the experience. The author clarifies the paradox that a cohesive, well-integrated self allows unitive, non-self-definitional experiences. The author attempts to work the cultural/clinical border by exploring oneness phenomena as they occur in art, religion, literature and the clinical consulting room. The author uses psychoanalytic tools to understand non-clinical experiences of oneness. Through compelling accounts of such experiences as described by artists, writers and meditators, psychoanalytic theorizing about oneness is illumined further. 相似文献

For the exploratory analysis of a matrix of proximities or (dis)similarities between objects, one often uses cluster analysis
(CA) or multidimensional scaling (MDS). Solutions resulting from such analyses are sometimes interpreted using external information
on the objects. Usually the procedures of CA, MDS and using external information are carried out independently and sequentially,
although combinations of two of the three procedures (CA and MDS, or multidimensional scaling and using external information)
have been proposed in the literature. The present paper offers a procedure that combines all three procedures in one analysis,
using a model that describes a partition of objects with cluster centroids represented in a low-dimensional space, which in
turn is related to the information in the external variables. A simulation study is carried out to demonstrate that the method
works satisfactorily for data with a known underlying structure. Also, to illustrate the method, it is applied to two empirical
data sets. 相似文献
