WebFeb 28, 2016 · Horseshoe priors are similar to lasso and other regularization techniques, but have been found to have better performance in many situations. A regression coefficient β i, where i ∈ { 1, D } predictors, has a horseshoe prior if its standard deviation is the product of a local ( λ i) and global ( τ) scaling parameter. WebThe horseshoe prior has proven to be a noteworthy alternative for sparse Bayesian estimation, but as shown in this paper, the results can be sensitive to the prior choice for the global shrinkage hyperparameter. We argue that the previous default choices are dubious due to their tendency to favor solutions with more unshrunk coefficients than ... golyhawhaw body preset
