  1. Columns show Bayesian estimates and credible intervals. Differences refer to differences from the pre-nesting intercept. When zero is not included within the credible intervals of the differences there is a detectable effect of this parameter on the dependent variable (printed in bold). Italic font indicates credible intervals that cross zero only marginally.
