Course Description

Discover Factor Analysis in R

The world is full of unobservable variables that can't be directly measured. You might be interested in a construct such as math ability, personality traits, or workplace climate. When investigating constructs like these, it's critically important to have a model that matches your theories and data.

This course will help you understand dimensionality and show you how to conduct exploratory and confirmatory factor analyses.

Learn to Use Exploratory Factor Analysis and Confirmatory Factor Analysis

You’ll start by getting to grips with exploratory factor analysis (EFA), learning how to view and visualize factor loadings, interpret factor scores, and view and test correlations.

Once you’re familiar with single-factor EFA, you’ll move on to multidimensional data, looking at calculating eigenvalues, creating screen plots, and more. Next, you’ll discover confirmatory factor analysis (CFAs), learning how to create syntax from EFA results and theory.

The final chapter looks at EFAs vs CFAs, giving examples of both. You’ll also learn how to improve your model and measure when using them.

Develop, Refine, and Share Your Measures

With these statistical techniques in your toolkit, you'll be able to develop, refine, and share your measures. These analyses are foundational for diverse fields, including psychology, education, political science, economics, and linguistics."

    In Chapter 1, you will learn how to conduct an EFA to examine the statistical properties of a measure designed around one construct.

    This course goes over how to perform factor analysis which can be helpful for creating psychometric tests. I do not work on this field, but it was extremely helpful to see how the tests can be ran R.

    Factor Analysis in R is a comprehensive course concerning exploratory and confirmatory factor analysis. It shows some of the main capabilities of the `psych` package related to factor analysis, and it also introduces the `sem` package for confirmatory factor analysis and touches upon the structural equations modelling. For both EFA and CFA, the fit metrics are shown and explained, and a link for a comprehensive overview of fit metrics is provided. However, in my opinion, this course lacks some useful information, in particular: 1. Some more details of the theory behind factor analysis. 2. Issues of validity and reliability. 3. More on pre-EFA exploration: vss, polychoric (and other) correlations. 4. Review of EFA estimation methods (minimum residual, maximum likelihood, principal axis, weighted least squares). 5. Review of rotation methods (and why we ever need them). 6. More tidy visualisation methods. Thank you for an interesting course!
