Thank you very much for this video :)

So when creating an equation for PC1, do I only use the two highest loadings for my coefficients? In this example it would be : PC2 = 0.885x + 0.808y....?

Thank you, dear professor, could you please mention some references which states that factor loadings above .3 or .5 are also acceptable?

[@brantazconflix3873]

You only have 5 items. Are you doing EFA in separate variable? Or only 1 variable contain 5 item?

how do I get to the start of the video

Quick question. What if most of "variance" is not in the first three PCAs, but distributed in MANY eg. PCA1-3 explains ONLY 15% of data variance?

[@geparada88]

But, what happens when you have a lot of factors (called items by you)? is it the case that you tend to have smaller squared Rs (loads)?

Hello, maybe someone can help me with a doubt.
Once one has the different factor loadings, and knowing that you have measured each of the items that correlate to the factor/component, can you obtain a numeric measure for the factor/component?

How do you get these numbers?

[@RoseWillowstone]

On SPSS you go to "Analyze" then on "Dimension Reduction" where you click on "Factor...". You put the variables you want in your Factor Analysis and boom, you have these numbers. You can further select different settings while you're on the "Factor..." window such as when you go to "Options..." you can select "Suppress small coefficients" and make the "Absolute value below" be .30 instead of .10.

Thanks this does nothing to help me understand what factor analysis is
