Nonparametric item response theory for multilevel test data

, 2022
Psychological measurement aims at measuring a psychological construct (e.g., an attribute, skill, or ability) by means of observable variables such as items on a test or questionnaire. To relate item scores to the psychological construct, item response theory (IRT) models are used.

Ordered latent class models in nonparametric item response theory

, 2004
Een geordend latente klassen model kan als een nonparametrisch itemresponstheorie model beschouwd worden. Dit biedt de mogelijkheid een nonparametrisch itemresponstheorie model op nieuwe manieren te schatten en te toetsen. Dit wordt in dit proefschrift nader onderzocht.

Smoothness-constrained Model for Nonparametric Item Response Theory

Smoothness-constrained Model for Nonparametric Item Response Theory
This paper is concerned with the nonparametric item response theory (NIRT) for estimating item characteristic curves (ICCs) and latent abilities of examinees on educational and psychological tests. NIRT models can estimate various forms of ICCs under mild shape restrictions, such as the constraints of monotone homogeneity and double monotonicity ...

Mathematical Optimization Models for Nonparametric Item Response Theory

Mathematical Optimization Models for Nonparametric Item Response Theory
This paper explores a mathematical optimization approach to nonparametric item response theory (NIRT). Specifically, we develop mathematical optimization models for estimating nonparametric item characteristic curves and latent abilities of examinees simultaneously.
