Bayesian density estimation for compositional data using random Bernstein polynomials We propose a Bayesian nonparametric model for single density estimation, for data in the p-dimensional simplex space, say S_p. The proposal is based on a particular class of multivariate Bernstein polynomials on S_p and extends the Dirichlet-Bernstein prior for density estimation, for data in a closed,…

A Nonparametric Bayesian Model for Local Clustering We propose a nonparametric Bayesian local clustering (NoB-LoC) approach for heterogeneous data. Using genomics data as an example, the NoB-LoC clusters genes into gene sets and simultaneously creates multiple partitions of samples, one for each gene set. In other words, the sample partitions are nested within the gene sets. Inference is guided by…

"Do Short Sellers Care About Corporate Hedging?" abstract We study the relationship between corporate hedging and short selling, using a novel data set on short sales of US equities over the period 2002-2009, and hand-collected data on corporate hedging. We document that hedging is associated with lower uncertainty, i.e., lower analyst forecast dispersion and greater breadth of ownership. This should…
