Notes: The table shows the ratio $σ_{u}^{2} / (σ_{u}^{2} + σ_{e}^{2})$ where $σ_{u}^{2}$ and $σ_{e}^{2}$ are, respectively, the estimated variances of $u_{s}$ and $e_{j s}$ in the random effects model $S u p p o r t_{j s} = μ + u_{s} + e_{j s}$ ⁠. Each cell in the table represents the results from a separate regression model. Sample sizes are rounded to the nearest 10.
