Kraemer, Helena Chmura – Psychometrika, 1981
Asymptotic distribution theory of Brogden's form of biserial correlation coefficient is derived and large sample estimates of its standard error obtained. Its relative efficiency to the biserial correlation coefficient is examined. Recommendations for choice of estimator of biserial correlation are presented. (Author/JKS)

Hedges, Larry V.; Olkin, Ingram – Psychometrika, 1981
Commonality components have been defined as a method of partitioning squared multiple correlations. The asymptotic joint distribution of all possible squared multiple correlations is derived. The asymptotic joint distribution of linear combinations of squared multiple correlations is obtained as a corollary. (Author/JKS)

Snyder, Conrad W., Jr.; Law, Henry G. – Multivariate Behavioral Research, 1979
As psychologists increasingly employ more elaborate and comprehensive data collection schemes, sophisticated analytic techniques will play an ever more important role in understanding behavioral data. This paper outlines one such promising technique, Tucker's three-mode factor analysis, which enables the researcher to explore new taxonomic…

Finkbeiner, Carl – Psychometrika, 1979
A maximum likelihood method of estimating the parameters of the multiple factor model when data are missing from the sample is presented. A Monte Carlo study compares the method with five heuristic methods of dealing with the problem. The present method shows some advantage in accuracy of estimation. (Author/CTM)

Owston, Ronald D. – Psychometrika, 1979
The method of scoring is used to obtain maximum likelihood estimates of the parameters in White and Clark's (EJ 075 122) learning hierarchy validation model. From the proportion of the population possessing only the superordinate skill in a pair of hierarchical skills, and its variance, the hypothesis of inclusion is tested. (Author/CTM)

Bergan, John R. – Journal of Educational Statistics, 1980
The use of a quasi-equiprobability model in the measurement of observer agreement involving dichotomous coding categories is described. A measure of agreement is presented which gives the probability of agreement under the assumption that observation pairs reflecting disagreement will be equally probable. (Author/JKS)

Johansson, J. K. – Psychometrika, 1981
An extension of Wollenberg's redundancy analysis (an alternative to canonical correlation) is proposed to derive Y-variates corresponding to the optimal X-variates. These variates are maximally correlated with the given X-variates, and depending upon the standardization chosen they also have certain properties of orthogonality. (Author/JKS)

Rastall, Paul R. – Linguistique, 1980
Introduces Hervey's axiomatic semantic theory as one that contains the fundamental Saussurian notion of "sign" and is based on a global view of language. Discusses the mutual dependence of semantic theory and linguistic theory, and states the conditions of applicability of the former in terms of formal, empirical, and methodological…

Jackson, Peter – Thrust: The Journal for Employment and Training Professionals, 1980
Discusses a 1976 survey of Comprehensive Employment and Training Act participants and factors affecting the success or failure of employment programs. (JOW)

Smith, J. MacGregor – Journal of the American Society for Information Science, 1981
Queuing networks, mixed integer programing, and expected utility theory are combined together to model the library building programing problem. Thirty-nine references are cited. (Author/FM)

Hubert, Lawrence J. – Psychometrika, 1979
Inference procedures appropriate for the analysis of nominal and ordinal data are discussed. Matching models are shown to be useful under certain constraints. (JKS)

Bloom, Howard S. – National Tax Journal, 1979
Argues that citizens' perceptions of their monetary self-interest can markedly influence their votes and that such self-interested voting requires clear definition of the alternatives, widespread publicity about the issues, and a simple presentation of what each alternative implies. Available from NTA-TIA, 21 East State Street, Columbus, OH 43215.…

Ihlanfeldt, Keith Ray – National Tax Journal, 1979
The direct estimates of the relationship between permanent income and property tax payments presented here suggest that the property tax on homeowners is progressive at the national level and generally proportional at the local level. Available from NTA-TIA, 21 East State Street, Columbus, OH 43215. (Author)

Levine, Richard A.; Ohman, Pamela A. – Psychometrika, 1997
Challenge studies can be used to see whether there is a causal relationship between an agent of interest and a response. An approach based on union-intersection testing is presented that allows researchers to examine observations on a single subject and test the hypothesis of interest. An application using psychological data is presented. (SLD)

Cheng, Patricia W. – Psychological Review, 1997
An integration of two different approaches to the psychology of causal induction is proposed that overcomes the problems associated with each. The proposal results in a causal power theory of the probabilistic contrast model of P. W. Cheng and L. R. Novick (1990). (SLD)
