Introduction to the Taxometric Method: A Practical Guide
Preface. Part 1. Introduction and Background. Introduction. Why Latent Structure Matters. The Classification Problem. Part 2. Taxometric Method. Data Requirements for Taxometrics. Taxometric… Expand
Determining the number of factors to retain in an exploratory factor analysis using comparison data of known factorial structure.
Exploratory factor analysis (EFA) is used routinely in the development and validation of assessment instruments. One of the most significant challenges when one is performing EFA is determining how… Expand

- 1 March 2010
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 taxometric… Expand
Clarifying boundary issues in psychopathology: the role of taxometrics in a comprehensive program of structural research.
Despite decades of debate, important questions about the boundaries that separate psychological disorder from normality and that distinguish 1 disorder from another remain largely unanswered. These… Expand
The latent structure of analogue depression: should the Beck Depression Inventory be used to classify groups?
Research on depression is often conducted with analogue samples that have been divided into depressed and nondepressed groups using a cutoff score on the Beck Depression Inventory (BDI). Although the… Expand
A Nontechnical Introduction to the Taxometric Method
We present a nontechnical introduction to the taxometric method for assessing latent structure and a number of refinements and extensions to it. Expand
Applying the Bootstrap to Taxometric Analysis: Generating Empirical Sampling Distributions to Help Interpret Results

- Computer Science, Medicine
- Multivariate behavioral research
- 29 June 2007
We present iterative algorithms for creating bootstrap samples of taxonic and dimensional comparison data that reproduce important features of the research data with good precision and negligible bias. Expand
Looking Inside the Fishbowl of Creativity: Verbal and Behavioral Predictors of Creative Performance
This study set out to identify specific task behaviors that predict observable product creativity in three domains and to identify which of those behaviors mediate the well-established link between… Expand
