“…In principle, the methods considered in this chapter can also be applied to other types of dependent data such as three-level, crossclassified, or multiple-membership data (for an overview, see Goldstein, 2011). For example, Wijesuriya et al (2020) and considered a variety of MI approaches for three-level data, and Grund et al (2023b) proposed JM and FCS approaches for the imputation of cross-classified data (see also Yucel et al, 2008). Especially in cross-classified data, the treatment of missing data comes with additional challenges due to the non-hierarchical structure of the data and the more complex pattern of dependency that they imply (Luo & Kwok, 2009;Meyers & Beretvas, 2006;Shi et al, 2010).…”
