“…A similar approach based on the structural equation model (SEM) paradigm has been developed by Boker and coworkers (Boker et al, 2004; Boker & Nesselroade, 2002), improved over time (Boker, Moulder, et al, 2019; Hu et al, 2014; Hu & Boker, 2016; McKee et al, 2020), and used in numerous studies (Chow et al, 2005; Deboeck & Boulton, 2016; Hardt et al, 2020; Pettersson et al, 2013; Steele & Ferrer, 2011). It is called the latent differential equation (LDE) method.…”
