Figure 1:

Prior distributions for the parameters of the varying intercepts and varying slopes linear mixed model. The prior for the grand mean parameter β₀ is a normal distribution with mean 0 and standard deviation 200 (Normal(0, 200)); the prior for the parameter representing the effect of gender, β₁, is Normal(0, 50); the priors for all the standard deviations are N ormal₊(0, 100); and the prior for the correlation between the random effects is a so-called LKJ(ν = 2) prior, which is explained in the main text.
