We propose a Bayesian approach to multidimensional scaling when the low-dimensional manifold is hyperbolic.

The vote Package: Single Transferable Vote and Other Electoral Systems in R

no code implementations • 11 Feb 2021 • Adrian E. Raftery, Hana Ševčíková, Bernard W. Silverman

We describe the vote package in R, which implements the plurality (or first-past-the-post), two-round runoff, score, approval and single transferable vote (STV) electoral systems, as well as methods for selecting the Condorcet winner and loser.
