Comparing the relative fit of categorical and dimensional latent variable models using consistency tests.
A number of recent studies have used Meehl's (1995) taxometric method to determine empirically whether one should model assessment-related constructs as categories or dimensions. The taxometricExpand
Simulating Multivariate Nonnormal Data Using an Iterative Algorithm
We present an alternative technique that involves sampling data from specified population distributions and identifying the intermediate correlation matrix through an iterative, trial-and-error process and show that it can generate data under a wide range of conditions. Expand
Differentiating Categories and Dimensions: Evaluating the Robustness of Taxometric Analyses
Interest in modeling the structure of latent variables is gaining momentum, and many simulation studies suggest that taxometric analysis can validly assess the relative fit of categorical andExpand
Metrics in Simulations and Games for Learning
This chapter introduces the approach taken by the Games for Learning Institute (G4LI) to assess learning and related learner variables, with a focus on the use of metrics obtained during game play and simulation exploration. Expand
Development and Validation of the College Campus Environment Scale (CCES): Promoting Positive College Experiences
One of the essential factors related to student success and satisfaction with a higher education experience is the college environment in which learning takes place. The purpose of this study was toExpand
