Supplement to Koller, Maier, & Hatzinger: "An Empirical Power Analysisof Quasi-Exact Tests for the Rasch Model: Measurement Invariance inSmall Samples"

This document is a supplementary text to "An Empirical Power Analysis of Quasi-Exact Tests for the Rasch Model: Measurement Invariance in Small Samples" by Koller, Maier, & Hatzinger (to be published in Methodology, ISSN-L 1614-1881), which covers all technical details regarding the simulation and its results. First, the simulation scenarios and the introduction of differential item functioning (DIF) are described. Next, the different populations' distributions that were investigated are discussed, and finally, actual type-I-error rates and empirical power are displayed for all simulated scenarios.
