This prior captures the belief that … WebThe horseshoe prior takes its name from the prior on κi, which is given by: pτ(κi) = τ π 1 1−(1 −τ2)κi (1 −κi)− 1 2κ −1 2 i. If τ = 1, this reduces to a Be(1 2, 2) distribution, which looks like a horseshoe. As illustrated in Figure 1, decreasing τ skews the prior distribution on κi towards

WebIn this study, we propose a method for incorporating multiple historical controls based on a horseshoe prior, which is a type of global-local shrinkage prior. The method assumes that historical controls follow the same distribution as the current control. In the case in which only a few historical controls are heterogeneous, we consider them to ...

It is symmetric around zero with fat tails and an infinitely large spike at zero. This makes it ideal for sparse models that have many regression coefficients, although only a minority of them is non- zero. cretech gmbh
