A Bayesian approach with frequentist validity has been developed to support inferences derived from a BLevel A^ in vivo-in vitro correlation (IVIVC). Irrespective of whether the in vivo data reflect in vivo dissolution or absorption, the IVIVC is typically assessed using a linear regression model. Confidence intervals are generally used to describe the uncertainty around the model. While the confidence intervals can describe population-level variability, it does not address the individual-level variability.

.....RACE AND GENDER DIHERENCES EN EDUCATIONAL ATTAINMENT, HILD OF STUDY, AND [NCREMENTS TO EARNINGS (EVIDENCE FROM UNIVERSITY OF ILLINOIS TRACER STUDIES AND NATIONWIDE EARNINGS DATA) Even at the upper extreme of the estimated confidence intervals, the SAT gap between more- and less-desirable schools is not meaningfully larger in markets with decentralized governance than in those with less Tiebout choice.

GOODWILL : CHARACTERISTICS AND IMPAIRMENT When MSAs are weighted equally, for example, rather than by the number of SAT takers or by the 17-yearold population (not shown, but similar to the SAT-taker weighting in Table 1.7), the choice effect is about one third as large as that shown here and confidence intervals do not reject zero. Nevertheless, there is no indication that Tiebout choice is associated with higher SAT scores once student background is controlled.56

ESSAYS ON EDUCATION INVESTMENT, INCOME INEQUALITY, AND ECONOMIC GROWTH Recall, moreover, that this thought experiment assumes a choice coefficient at the upper limit of the confidence interval. At the point estimate, choice reduces the gradient of SAT scores with respect to student quality. The models in Table 1.4 reject a sizableby any reasonable standardeffect of choice on the test score gradient.

PUBLIC & PRIVATE MANAGEMENT: FUNDAMENTALLY ALIKE OR DIFFERENT? We can imagine as a thought experiment fully decentralizing school governance in Miami-Dade County, which is served by a single district.53 Figure 1.7 displays the actual distribution of peer groups and school average SAT scores in Miami, as well as the counterfactual distribution that might be observed if the Miami choice index were changed to one and if the effect of choice were at the upper limit of its confidence interval.

THE ROLE OF EDUCATION IN ECONOMIC TRANSITION AND POLITICAL TRANSFORMATION IN POST-COMMUNIST COUNTRIES The answer appears to be no. Note that the within-MSA gradient of school average SAT scores with respect to student characteristics is 1.74 (from Column A of the same table). Even at the upper limit of the confidence interval, a move from unified governance to complete decentralization accounts for just over ten percent of this gradient.
