Estimation Precision of Variance Components: Revisiting Generalizability Theory

12:00pm EDT

Please consult the event program for date, time and location.

Presented at: NCME 2016

In this coordinated session of three presentations, the overarching theme is the estimation precision of variance components (VCs) in generalizability theory (G theory). In the first presentation, the authors discuss the adverse effects of non-additivity on the estimation precision of VCs.

As a follow-up study, the second presentation focuses on the identification of non-additivity by use of Tukey’s single-degree-freedom test.

Finally, the third presentation extends our theme in a multivariate context and touches on the estimation precision of construct-irrelevant VCs in subscore profile analysis.
