It's 12:30 AM. The kids are in bed and I just did some reading, trying to wrap my head around the reasons (advantages and uses of factor analysis). This video was easier to understand than the reading and well-explained enough that I didn't fall asleep despite the hour. Kudos to you! On to part 2 as a result!

My teacher tried to explain the same thing in a 1.5 hour long class, you did better in just 8 minutes. Thanks!

This is by far the best introductory video to factor analysis. Thank you!

I am writing my finance thesis which requires the statistical method to test certain strategies. And This video helps me a lot for continuing constructing my finance strategy and testing its performance.
Great job Ben!

Fabulous lesson. I'm currently in a Tests and Measures master's class. We need to do an assessment review of the Big Five, which as you know analyzes data using the statistical procedure of factor analysis; something not yet covered by my class. It doesn't help our professor doesn't lecture. We are made to read the book and loads of research, but we are left to extrapolate meaning. This is one class I regret taking online during COVID. Thank you for the clarification.

Ohhh… just been slogging through Manly textbook chapter on Factor Analysis, while also watching a great deal of this series, and getting more & more confused, until the chapter’s conclusion defined a few terms that really were needed at the start. Turns out this youtube series is mostly pertinent to CONFIRMATORY Factor Analysis, whereas Manly (& my upcoming assignment) is focussing on EXPLORATORY Factor Analysis. Which is … kinda different, back to front. Thankyou though! Things are definitely more clearly explained than the Manly textbook or my lecturer.

Thanks for the wonderful lecture in EFA.
I have a question:
The assumption that the measurement errors are not correlated with the factors and not correlated between them, this assumption isn't valid in reality?

Thank you Professor. It is great revision. You made it simple and effective.

You've labelled the hidden factors as depression and anxiety but it's really just 2 factors that explain, right? ie dimensionalty reduction but who's to say what the factors really are?

Thank you Ben. I am so grateful to you because of the excellent material that you have explained so well ..

Captain, we need to reduce the dimensionality in order to increase the predictive power of the model!

Well explained thanks, but:
What do you mean by "unobserved" variables (depression and anxiety)? If they're unobserved that would mean (I assume) that they're not measured, in which case how would they be factored in?
