Parallel analysis for PCA and EFA in SPSS using O'Connor's syntax @mikecrowson2462

This video provides a demonstration of how to use Brian O'Connor's syntax (found HERE: oconnor-psych.ok.ubc.ca/nfactors/nfactors.html) to perform parallel analysis using SPSS. In the video, I demonstrate how to perform parallel analysis in the context of Principal Components Analysis and in the context of Exploratory Factor Analysis (using Principal Axis factoring).

Some of the discussion points I raise are addressed in:

Fabrigar, L. R., & Wegener, D. T. (2012). Exploratory factor analysis. Oxford University Press.
