95% confidence ellipse in a PCA biplot

[#1]

Hello, everyone.

I'm currently conducting a PCA biplot analysis and would like to add a 95% confidence ellipse for each of the three groups I'm analyzing. While I know this is possible in other software like R, I'm unsure how to achieve this in JMP Pro 17. Could someone help me?

I attached two figures, an exemple of a 95% confidence ellipse that I want to do and my PCA biplot.

Hi @vtrbrn25 ,

Have you tried using  Scatterplot 3D under Graph menu? There are options in the red triangle that allow PCA and to show a confidence ellipse.
