When modeling the relationship between two nominal categorical variables, it is often desirable to include covariates to understand
how individuals differ in their response behavior. Typically, however, not all the relevant covariates are available, with
the result that the measured variables cannot fully account for the associations between the nominal variables. Under the
assumption that the observed and unobserved variables follow a homogeneous conditional Gaussian distribution, this paper proposesRC(M) regression models to decompose the residual associations between the polytomous variables. Based on Goodman's (1979, 1985)RC(M) association model, a distinctive feature ofRC(M) regression models is that they facilitate the joint estimation of effects due to manifest and omitted (continuous) variables
without requiring numerical integration. TheRC(M) regression models are illustrated using data from the High School and Beyond study (Tatsuoka & Lohnes, 1988).

In this paper we describe the Priestley space of a quasi-Stone algebra and use it to show that the class of finite quasi-Stone
algebras has the amalgamation property. We also describe the Priestley space of the free quasi-Stone algebra over a finite
set.

The U.S. Constitution is a blueprint for the design of a government which reflects the consistent application of an understanding of the emotions and interests driving the political activity of individuals and groups. This understanding is articulated in the writings of key proponents of the Constitution, and clarified by its historical and philosophical context. Their theories are congruent with psychoanalytic perspectives on narcissism, leadership, group dynamics, and the role of transitional space in cultural life. The concept of interests, reformulated in psychoanalytic terms, is a useful addition to our understanding of political behavior. 相似文献

When a number of two-stimulus relations are established through training within a set of stimuli, other two-stimulus relations often emerge in the same set without direct training. These, termed "transitive stimulus relations," have been demonstrated with a variety of visual and auditory stimuli. The phenomenon has served as a behavioral model for explaining the emergence of rudimentary comprehension and reading skills, and the development of generative syntactic repertoires. This article considers the range of relations that can arise between a given number of stimuli in a class, the number of directly established two-stimulus relations necessary for the emergence of transitive relations, the forms that training sets of stimuli can take, and the number of transitive two-stimulus relations that can be induced without direct training. The procedures needed to establish and assess transitive stimulus control, the possible interactions between the training and testing procedures, and the constrainst these interactions place upon the analysis of transitive stimulus control are also examined. The present analysis indicates that in a transitivity test, choice among such stimuli may be controlled by (1) the relation between the sample and the positive comparison stimulus (transitive stimulus control), (2) the relation between the sample and the negative comparison stimulus (S- rule control), and (3) possible discriminative properties that may inadvertently be established in the positive and negative comparison stimuli (valence control). Methods are described for distinguishing these three forms of stimulus control. 相似文献

Sprague-Dawley rats were studied to learn whether gestation in the near-zero gravity, high radiation environment of space
impacts selected mammalian postnatal events. Ten rats spent days nine to twenty of pregnancy aboard the space shuttle orbiterAtlantis (STS-66). Their movement, was studied shortly after return to Earth; subsequently, several of their offspring were cross-fostered
and examined through postnatal day 81 (P81) for whole body growth and somatic motor development. Values for the flight animals
were compared to ground-based control groups. Relative to controls, the pregnant flight rats showed a marked paucity of locomotion
during the first few hours after returning to Earth. There was greater likelihood of perinatal morbidity for the offspring
of flight dams when compared to the control groups. Whole body weight of surviving offspring, averaged for each group separately,
showed typical sigmoidal growth curves when plotted against postnatal age. The flight group for our study had a larger ratio
of female to male pups, and that was sufficient to account for the lower average daily weight gained by the flight animals
when compared to the control groups. Walking was universally achieved by P13 and preceded eye opening which was complete in
all pups by P17. Thus, both of these developmental horizons were attained on schedule in the flight as well as the control
rats. Characteristic changes were observed in hind limb step length and gait width as the pups grew. These patterns occurred
at the same time in each group of rats. Therefore, prenatal space flight from days nine to twenty of gestation did not interfere
with the establishment of normal patterns for hind paw placement during walking. 相似文献

基于特征的联想 总被引:2,自引:0,他引:2
联想是认知科学中十分重要的现象,许多学者进行过不同角度的研究,获得了许多有意义的结果。根据有关对象(0bject)描述的基本概念,从联接机制的角度对联想问题进行一些探讨,并提出一个基于特征的联想模型FBCAM(FeatureBasedConnectionistAssociationModel)。在FBCAM中,对象由其特征及特征的伴随值描述,从而可以获得更为精确的描述。对象的全部特征构成描述模式,伴随值则相应地构成伴随向量。在此基础上可以细致地刻画概念之间的相似性,并可对联想及注意机制进行细致的模拟与分析。文中利用联接机制的思想实现了FBCAM并给出该系统的部分运行结果,表明FBCAM可以较合理地解释联想过程 相似文献

Ak-dimensional multivariate normal distribution is made discrete by partitioning thek-dimensional Euclidean space with rectangular grids. The collection of probability integrals over the partitioned cubes is ak-dimensional contingency table with ordered categories. It is shown that loglinear model with main effects plus two-way interactions provides an accurate approximation for thek-dimensional table. The complete multivariate normal integral table is computed via the iterative proportional fitting algorithm from bivariate normal integral tables. This approach imposes no restriction on the correlation matrix. Comparisons with other numerical integration algorithms are reported. The approximation suggests association models for discretized multivariate normal distributions and contingency tables with ordered categories.The contingency-table approach occurred to me while I was collaborating with Paul Holland of the Educational Testing Service in 1985 on bivariate dependence functions. Holland maintains a belief that the continuous can learn from the discrete. This work is a reassertion of his claim.This research was sponsored by the National Science Council, Republic of China. 相似文献

We consider latent variable models for an infinite sequence (or universe) of manifest (observable) variables that may be discrete, continuous or some combination of these. The main theorem is a general characterization by empirical conditions of when it is possible to construct latent variable models that satisfy unidimensionality, monotonicity, conditional independence, andtail-measurability. Tail-measurability means that the latent variable can be estimated consistently from the sequence of manifest variables even though an arbitrary finite subsequence has been removed. The characterizing,necessary and sufficient, conditions that the manifest variables must satisfy for these models are conditional association and vanishing conditional dependence (as one conditions upon successively more other manifest variables). Our main theorem considerably generalizes and sharpens earlier results of Ellis and van den Wollenberg (1993), Holland and Rosenbaum (1986), and Junker (1993). It is also related to the work of Stout (1990).The main theorem is preceded by many results for latent variable modelsin general—not necessarily unidimensional and monotone. They pertain to the uniqueness of latent variables and are connected with the conditional independence theorem of Suppes and Zanotti (1981). We discuss new definitions of the concepts of true-score and subpopulation, which generalize these notions from the stochastic subject, random sampling, and domain sampling formulations of latent variable models (e.g., Holland, 1990; Lord & Novick, 1968). These definitions do not require the a priori specification of a latent variable model.The authors made equivalent contributions to the results of this article.

TheRC(M) association model (Goodman, 1979, 1985, 1986, 1991) is useful for analyzing the relationship between the variables of a 2-way cross-classification. The models presented here are generalizations of theRC(M) association model for 3-way tables. The family of models proposed here, 3-mode association models, use Tucker's 3-mode components model (Tucker, 1964, 1966; Kroonenberg, 1983) to represent either the three factor interaction or the combined effects of two and three factor interactions. An example from a study in developmental psychology (Kramer & Gottman, 1992) is provided to illustrate the usefulness of the proposed models.I thank Stanley Wasserman, Laurie Kramer, Ulf Böckenholt, Larwence Hubert, Jeffrey Tanaka, and five anonymous reviewers for valuable comments. 相似文献
