“…18 For example, in the 2006 cross section, out of the twenty-one regressions of the first column of Table 1, none of the ρ a parameters have a greater than 90 percent chance of exceeding the mean of the prior distribution (0.5), and only three have greater than a 75 percent chance of being greater than the prior mean (only casework form, link to FirstGov, and video), or about what one would expect to observe simply from random variation. These findings regarding local-level dependence reinforce those from other studies that find relatively few district-level observed variables that are predictive of website quality (Adler, Gent, and Overmeyer 1998, 591;Cooper 2004, 352;Druckman, Kifer, and Parkin 2007;Druckman et al 2009, 17;Ferber, Foltz, and Pugliese 2005, 147;Esterling, Lazer, and Neblo 2011). The lack of all dependence at this level further demonstrates the absence of unobserved causal variables measured at the district level.…”
