Testing for Differentially Functioning Indicators Using Mixtures of Confirmatory Factor Analysis Models

Mann, Heather Marie - 2009

Heterogeneity in measurement model parameters across known groups can be modeled and tested using multigroup … characteristics to capture heterogeneity and have the potential to be used to test measurement invariance. The current study … sample sizes, more noninvariant factor loadings, and larger amounts of heterogeneity are needed to distinguish different …

Accommodating Complex Substitution Patterns in a Random Utility Model of Recreational Fishing

Hunt, Len M.; Boxall, Peter C.; Boots, Barry - 2007

We employed a cross-nested logit (CNL) model that permits a rich pattern of substitution among alternatives within a closed form choice model. The specification we employed is ideal for applications with many choice alternatives, such as the 431 fishing sites in this application. The CNL model...

An Empirical Investigation of Unscalable Components in Scaling Models

Braaten, Kristine Norene - 2009

Guttman (1947) developed a scaling method in which the items measuring an attribute can be ordered according to the strength of the attribute. The Guttman scaling model assumes that every member of the population belongs to a scale type and does not allow for response errors. The Proctor (1970)...
