scores plot for PCA

Created: May 15, 2022 09:50 AM  |  Last Modified: Jun 8, 2023 5:49 PM (1681 views)

The scores plot has a circle inside the scatterplot.  Does this represent a confidence interval or is it more for decorative purposes?  If the former, can the confidence interval be changed?

Hi,

I believe that you are referring to the Loading Plot, where the circle represents the maximum possible contribution of each variable (i.e., Distance from zero = 1). The length of the vectors (arrows) represents the relative contribution of each variable to the principal components displayed.

Best,
