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

[jennifergarcia]

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....?

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?

[brantazconflix]

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

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)?

[GBM]

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?

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