THE GRADED UNFOLDING MODEL: A UNIDIMENSIONAL ITEM RESPONSE MODEL FOR UNFOLDING GRADED RESPONSES

ETS Research Report Series, 1996
ABSTRACTBinary or graded disagree‐agree responses to attitude items are often collected for the purpose of attitude measurement. Although such data are sometimes analyzed with cumulative measurement models, recent investigations suggest that unfolding models are more appropriate (Roberts, 1995; Van Schuur & Kiers, 1994).

Latent Trait Models and Dichotomization of Graded Responses

Psychometrika, 1986
This paper discusses the compatibility of the polychotomous Rasch model with dichotomization of the response continuum. It is argued that in the case of graded responses, the response categories presented to the subject are essentially an arbitrary polychotomization of the response continuum,

A Note on the Equivalence of the Graded Response Model and the Sequential Model

Psychometrika, 2001
This paper concerns items that consist of several item steps to be responded to sequentially. The item score X is defined as the number of correct responses until the first failure. Samejima's graded response model states that each step h =1,...,

A Gibbs‐INLA algorithm for multidimensional graded response model analysis

British Journal of Mathematical and Statistical Psychology, 2023
Abstract In this paper, we propose a novel Gibbs‐INLA algorithm for the Bayesian inference of graded response models with ordinal response based on multidimensional item response theory. With the combination of the Gibbs sampling and the integrated nested Laplace approximation (INLA), the new framework avoids the cumbersome tuning ...

Generalized Fiducial Inference for Logistic Graded Response Models

Psychometrika, 2017
Samejima’s graded response model (GRM) has gained popularity in the analyses of ordinal response data in psychological, educational, and health-related assessment. Obtaining high-quality point and interval estimates for GRM parameters attracts a great deal of attention in the literature.

The Polychotomous Rasch Model and Dichotomizatipn of Graded Responses

1984
Abstract This oaner discusses the compatibility of the polychotomous Rasch model with dichotomization of the response continuum. It is argued that in the case of graded responses, the response categories presented to the subject are essentially an arbitrary oo-lychotomization of the response continuum, ranging e.g.

A graded response model for measuring person reliability

British Journal of Mathematical and Statistical Psychology, 2009
This paper extends Lumsden's fluctuation model to the graded response case and, from the resulting basic scaling model, develops a one‐dimensional item response theory graded response model (GRM). Under some additional assumptions, it follows that the item category response functions (ICRFs) can be closely approximated by the ICRFs of the standard GRM ...

The Graded Response Differential Discrimination Model Accounting for Extreme Response Style

Multivariate Behavioral Research, 2017
Extreme response style or, more generally, individual differences in response spacing have been shown to be an influential bias when analyzing questionnaire data. Recently a promising model adjusting for this bias - the differential discrimination model - has been proposed.

Modeling of Impact Response of Composite Graded Structure

Volume 8: Mechanics of Solids, Structures and Fluids; Vibration, Acoustics and Wave Propagation, 2011
The work presented in this paper is a continuation of a study on exploring energy absorbing characteristics of a composite functionally graded structure found in a banana peel [1]. The impact behavior of peel structure under strain rates ranging from 4000 s−1 to 15000s−1 are studied.

Graded Response Model

1997
The graded response model represents a family of mathematical models that deals with ordered polytomous categories. These ordered categories include rating such as letter grading, A, B, C, D, and F, used in the evaluation of students’ performance; strongly disagree, disagree, agree, and strongly agree, used in attitude surveys; or partial credit given ...
