Ever wonder what Factor Analysis is and how it compares with Principal Component Analysis? Look no further! This is a guide to further theoretical and applied understanding of Factor Analysis! This comes with a code demonstration in R.

Forgot what Principal Components is?

Check out how to compute factor scores!

Excelent video! Keep up with the good work, you are helping a lot of distressed students!

thanks so much...I'm working on my thesis and this was extremely helpful... 🙃

After factor analysis, how we can create an index or indicator?

Hi, I'm having trouble using the data set in the link. It downloads as a .arff file and I've tried using both foreign and Weka packages to import the data with no success

how to use output of factor analysis output/factors in clustering or other ML algo like classification?

[tomthomas]

while applying the pa and ml method the values for the h2 and u2 is not showing and also i have 10 variables but for 3 factors the cumulative variance is 0.43. so what to do?

Thank you for this video! Do you have any suggestions on how to handle missing data in factor analysis?

How do you know the # of factors that you look for? Is this based from your research context, or can you read the is from the date by experimenting with more or less factors? & what if you have contrasting factor loadings, can you invert these? (I.E.: I have question on how challenging something is, and after how easy it is which is in contrast)

Do you have a video explaining Tucker’s? Thanks

[ramziraspaty]

I have a question. So, you arbitrarily stated the number of factors you used in this video and you said that a more 'scientific' way of determining numbers of factors could be done by using scree plot (elbow method). You know that some data don't have a good scree plot diagram, right? If that's the case, can I use like the Eigenvalue thing? Thank you so much!

My analysis for
factor analysis is returning NA- not available

Half of me is thinking "You're just making this all up" haha
