Title: Inferential PCA and RNA structure analysis Authors:  Benjamin Eltzner - Georg-August-University of Goettingen (Germany) [presenting]

Abstract: RNA backbone geometry is canonically described in terms of dihedral angles, which are represented on a torus. PCA on a torus is challenging and so is variance analysis and dimension reduction: There is always a price to pay. We pay a small price and develop an asymptotic theory for our approach that gives rise to two-sample tests via bootstrapping.
