ABSTRACT
In chapter 4, I highlighted several problematic aspects of post hoc model fitting in structural equation modeling. Indeed, so common is this practice, and so frequently is it conducted with little to no regard for the substantive meaningfulness of the respecified models, that concerned researchers have provided a variety of different means by which such models can be tested more stringently (see Anderson & Gerbing, 1988; Cudeck & Henly, 1991; MacCallum, 1995; MacCallum et al., 1992, 1993 ). In chapter 4, I noted that one approach to addressing problems associated with post hoc model fitting is to apply some mode of cross-validation analysis; this is the focus of the present chapter. Before walking through this procedure, however, let's first review some of the issues related to cross-validation.
