= Continuous spike-and-slab prior
A <continuous spike-and-slab prior> mixes a narrow continuous <probability distribution> around zero with a much wider component. It permits practical effect selection while retaining a continuous <posterior density>. Its narrow component is not the exact-zero mass of a <point-null mixture prior>. A latent component indicator aids computation; a wide-component draw can still have small magnitude, so posterior effect thresholds and component membership answer different questions.
