sion 3.5 of the <code>RoBMA</code> package, the
hierarchical meta-analysis and meta-regression can use the
spike-and-slab model-averaging algorithm described in <a href="FastRoBMA.html">Fast Robust Bayesian Meta-Analysis via Spike and
Slab Algorithm</a>. The spike-and-slab model-averaging algorithm is a
more efficient alternative to the bridge algorithm, which is the current
default in the <code>RoBMA</code> package. For non-selection models, the
likelihood used in the spike-and-slab algorithm is equivalent
