Motivated by the analysis of torsion (dihedral) angles in the backbone of proteins, we investigate clustering of bivariate angular data on the torus [−𝜋,𝜋) × [−𝜋,𝜋). We show that naive adaptations ...

It is shown, by example, how this can serve as a basis for cluster identification. Management Science is a cross-functional, multidisciplinary examination of advances and solutions supporting enhanced ...
