Density of \(\sqrt {n}\alpha _{i}+\varepsilon _{is}\). The panels on the left and right correspond to σi=1 and σi∼IG(2,1) respectively, where IG denotes the inverse-gamma distribution. The red curve is the density of the standard normal distribution. The blue and green curves are the densities of \(\sqrt {n}\alpha _{i}+\varepsilon _{is}\) with \(\mathbb {P}(\sqrt {n}\alpha _{i}=0)=0.8\) and \(\mathbb {P}(\sqrt {n}\alpha _{i}=2)=0.2\), and \(\mathbb {P}(\sqrt {n}\alpha _{i}=0)=0.8\) and \(\mathbb {P}(\sqrt {n}\alpha _{i}=5)=0.2\), respectively
