Results for the level-2 parameters of the OMM. We use the posterior medians as point estimates, and the SD and 95% central credible intervals (CCIs) represent the uncertainty. Note that the parameters Σ(ε)₁₁ and Σ(ε)₂₂ are the variances of the random logit deviations ε₁₂ and ε₂₁, respectively, and Σ(ε)₁₂ is the covariance between these two random effects.
