A Note on the Usefulness of Constrained Fourth-Order Latent Differential Equation Models in the Case of Small T

Hardt, Katinka; Boker, Steven; Bergeman , Cindy S.

Constrained fourth-order latent differential equation (FOLDE) models have been proposed (e.g., Boker et al. 2020) as alternative to second-order latent differential equation (SOLDE) models to estimate second-order linear ...

Robustness of Individual Score Methods against Model Misspecification in Autoregressive Panel Models

Hardt, Katinka; Hecht, Martin; Voelkle, Manuel

Different methods to obtain individual scores from multiple item latent variable models exist, but their performance under realistic conditions is currently underresearched. We investigate the performance of the regression ...

Testing Students with Special Educational Needs in Large-Scale Assessments – Psychometric Properties of Test Scores and Associations with Test Taking Behavior

Pohl, Steffi; Südkamp, Anna; Hardt, Katinka; Carstensen, Claus H.; Weinert, Sabine

Assessing competencies of students with special educational needs in learning (SEN-L) poses a challenge for large-scale assessments (LSAs). For students with SEN-L, the available competence tests may fail to yield test ...

Where Have the Persons Gone?

An Illustration of Individual Score Methods in Autoregressive Panel Models

Hardt, Katinka; Hecht, Martin; Oud, Johan H. L.; Voelkle, Manuel

Much effort has been made to develop models for longitudinal data analysis, but comparably less attention has been paid to the use of individual specific values on latent variables in longitudinal models. In a tutorial ...
