The Hierarchical Organization of Cognitive Abilities: Restoring General Intelligence Through the Use of Linear Structural Relations (LISREL).
Peer reviewed Peer reviewed
Undheim, Johan Olav; Gustafsson, Jan-Eric – Multivariate Behavioral Research, 1987
The hypothesis that fluid intelligence is equivalent to the factor of general intelligence is investigated using LISREL to specify higher-order models in reanalyses of three sets of psychometric data from subjects 11, 13, and 15 years old. The three studies showed fluid intelligence to be equivalent with a general factor. (LMO)

Hierarchical vs. Non-Nested Test for Contrasting Expectancy-Valence Models: Some Effects of Cognitive Characteristics.
Peer reviewed Peer reviewed
Butler, John K.; Womer, Norman Keith – Multivariate Behavioral Research, 1985
The study tests the appropriateness of multiplicative versus additive expectancy-valency models for grouping motivational force decisions of 82 undergraduate students. Arguments are offered favoring a non-nested regression models analysis over a traditional hierarchical analysis of nested regression models. Discriminant analysis indicated one of…

Genotype-Environment Covariance for Multiple Phenotypes: A Multivariate Test Using Adopted and Nonadopted Children.
Peer reviewed Peer reviewed
Baker, Laura A. – Multivariate Behavioral Research, 1989
A bivariate generalization of the genotype-environment covariation (GEC) is presented. A multivariate procedure for detecting univariate and bivariate GEC is also described and illustrated via a study of 136 adopted and 125 non-adopted 4-year-old children. (SLD)
