DOI: 10.1177/01466216221108136
Abstract: A common practice of linking uses estimated item parameters to calculate projected scores. This procedure fails to account for the carry-over sampling variability. Neglecting sampling variability could consequently lead to understated uncertainty for Item Response… read more here.

DOI: 10.3389/fpsyg.2023.1003756
Abstract: Item response tree (IRTree) models are theorized to extract response styles from self-report data by utilizing multidimensional item response theory (IRT) models based on theoretical decision processes. Despite the growing popularity of the IRTree framework,… read more here.
