WebA new interpretation of the horseshoe model is presented, and extensions to logistic regression and alternative hierarchies, such as horseshoe+, are discussed. Due to the conjugacy of the proposed hierarchy, Chib's algorithm may be used to easily compute the marginal likelihood of the model.

A new interpretation of the horseshoe model is … WebWe will describe three main strengths of the horseshoe estimator. First, it is highly adaptive, both to unknown sparsity and to unknown signal-to-noise ratio. Second, it is robust to large, outlying signals, as we will demonstrate analytically using the 2 representation theorem of Pericchi and Smith (1992).
