Rolf Sundberg, Uwe Feldmann
2016 Journal of Multivariate Analysis  
. • For large p, factor scores can be estimated with high precision (n need not be large). • For large p, an old iteration method converges fast and with no inadmissible values. a b s t r a c t In an approach  ...  aiming at high-dimensional situations, we first introduce a distribution-free approach to parameter estimation in the standard random factor model, that is shown to lead to the same estimating equations  ...  Acknowledgment We are grateful to an anonymous referee for valuable and constructive criticism.  ...

A Deep Learning Algorithm for High-Dimensional Exploratory Item Factor Analysis [article]

Christopher J. Urban, Daniel J. Bauer
2021 arXiv   pre-print
In this work, we investigate a deep learning-based VI algorithm for exploratory item factor analysis (IFA) that is computationally fast even in large data sets with many latent factors.  ...  We provide a real data application that recovers results aligning with psychological theory across random starts.  ...  Other marginal likelihood-based parameter estimation methods for exploratory IFA avoid approximating high-dimensional integrals and are therefore more computationally efficient.  ...

High-dimensional Exploratory Item Factor Analysis by A Metropolis–Hastings Robbins–Monro Algorithm

Li Cai
2009 Psychometrika  
A Metropolis-Hastings Robbins-Monro (MH-RM) algorithm for high-dimensional maximum marginal likelihood exploratory item factor analysis is proposed.  ...  It is shown that when the dimensionality is high, MH-RM has advantages over existing methods such as numerical quadrature based EM algorithm.  ...  JML computations iterate between two stages that are similar to the first and last stages in MH-RM: (1) replacing the unobserved factor scores with modal estimates given current item parameters, and (2  ...
