Determining number of factors: Exploratory factor analysis (EFA) using RStudio and EFA.dimensions

This video provides a demonstration of how to use the EFA.dimensions package with RStudio to make a determination of the number of factors that may explain the intercorrelations among a set of measured variables. I use an example and data from https://journals.plos.org/plosone/art... . A copy of the Excel data file can be downloaded here: https://docs.google.com/file/d/1Q8H43... A copy of the Powerpoint slides I reference in the video can be accessed here: https://docs.google.com/file/d/11jMov... A text file containing the code used in this video can be downloaded here: https://drive.google.com/file/d/1b9UJ... Link to EFA.dimensions documentation: https://cran.r-project.org/web/packag... Be sure to check out my blog, where I discuss the issue of over- and under-factoring: https://mikesquanthub.blogspot.com/20... consequences of over- versus under-factoring.html
