Horshoe prior
WebA special shrinkage prior to be applied on population-level effects is the (regularized) horseshoe prior and related priors. See horseshoe for details. Another shrinkage prior is the so-called lasso prior. See lasso for details. In non-linear models, population-level effects are defined separately for each non-linear parameter.
