Exploratory Factor Analysis with SAS

Let’s Bring Replication to EFA

Authors can (and, we argue, should) directly estimate the replicability of their exploratory factor analyses reported in scientific journals. Authors (e.g., Thompson, 2004) have introduced replicability procedures for EFA, similar to those procedures considered best practices in validation of prediction equations in multiple regression (Osborne, 2000, 2008). Although few authors perform the procedure, we hope you will see the intuitive appeal.

Specifically, since the goal of EFA is usually to infer or explore the likely factor structure of an instrument when used within a particular population, it is important to know whether a factor structure within a particular data set is likely to be observed within another, ...
