The priors used for the sensitivity analyses of the Bayesian regressions.

The student’s t(df, μ, σ) distribution has parameters df = degrees of freedom, μ = location (the median) and σ = scale, while the normal(μ, σ) has parameters μ = mean and σ = standard deviation. Remember that these distributions refer to the intercept and slope of a z-scored predictor (i.e., one with mean 0 and standard deviation 1) that is expected to have a weak and possibly negative effect.
