(A) Logratio analysis of the Rabbits data, aiming to explain the total logratio variance. (B) Principal component analysis of the additive logratios with reference component microbial gene number 856, showing a geometry practically identical to the exact logratio geometry (Procrustes correlation = 0.9991). The two groups of points are due to two sequencing laboratories, indicated here by F and S.
