Posterior distributions (solid lines) for the treatment effect and within-period intracluster correlation, obtained from the analysis of a randomly-selected simulated dataset for a SW design with S=1,T=5,m=10, true treatment effect θ=0, and intracluster correlation parameters ρ₁=0.1, and r=1. Prior distributions (dashed lines) are overlaid for reference. Note that the prior for the treatment effect is N(0,10⁴) with a probability density of 0.004 at θ=0
