The validity of the use of such risk measures in burden of disease studies in other countries is disputable, since air pollution mixtures (for which PM10 is an indicator) and average population susceptibility may vary between countries [ 11, 56] (Table 2, section 8).
In the case of the NAAQS, Bachmann (2007) summarizes the history of setting NAAQS, and McClellan (2011) emphasizes the role of scientific information in informing the EPA Administrator's policy judgments on the level and statistical form of the NAAQS for a particular indicator and averaging time for a specific criteria pollutant.
Polychoric correlations [ 32, 33] were calculated between responses to the IPC subscales' indicators, and the average interitem correlation was examined for each hospital site.
One-third of moonlighters (33.7%) reported any of these type 2 indicators, and the average score of the MCA composite index derived from these variables was positive at 0.422.
Three criteria were applied to assess convergent validity: internal consistency, indicator reliability, and average variance extracted (AVE).
In contrast to more pessimistic predictions, humanity has not collapsed, and, on the contrary, in the last 1,000 years, life expectancy has increased significantly, violence indicators have decreased, and average income has grown exponentially.
Using PPPs, the basic performance indicators such as coverage probability and average rate of a UE are analyzed in [7 10].
From these figures, we see that the contribution substantially varies across indicators and therefore a simple average of the indicator variable would probably not well describe wealth.
One of the strengths of QCA in this research project is the focus on uniformities and near-uniformities instead of average indicators and trends.
In this sense, for example, Italian Regulations based on the EU Directive 2008/98/EC suggest the Safety Potential (SAPO), an economical performance indicator relying on accident rates and average accident social costs, while predictive methods are not explicitly provided.
