Principal Component Analysis Weights

How are the Principal Component Analysis weights supposed to work? I can’t wrap my head around what that table means, because those are not the coefficients.

Thank you

Hi Atilio,

The weights here are squares of coefficients.
We show squared values here, since they always add up to 1, which we think is more intuitive when you are trying to understand which principal components original variables are made up of.

Thank you,
