Ellipses in factor analysis

Mahmood Naderan-Tahan
Hi

In the example shown in [1], there is command that adds ellipses in the individual map.


fviz_mfa_ind(res.famd,
             habillage = "Label", # color by groups
             palette = c("#00AFBB", "#E7B800", "#FC4E07"),
             addEllipses = TRUE, ellipse.type = "confidence",
             repel = TRUE # Avoid text overlapping
             )

Where can I find more information about what is that ellipse exactly and how that is defined? For example, in the at figure, I don't know why 1VAU which is in red, is not in the red ellipse. Any note about that?
