How does Compete estimate site traffic and Internet rank?

"Compete triangulates multiple data sources, including ISP, Panel &
Toolbar to estimate U.S. traffic. Compete has developed a unique
methodology created by experts in the fields of mathematics,
statistics and the data sciences to aggregate, transform, enhance and
normalize data in order to estimate U.S. Internet traffic. Based on
the daily web usage of more than two million members (and growing!) of
the Compete community, Compete calculates and estimates total traffic
and rank for nearly every site on the web. We use rigorous statistics
to make sure our estimates balance demographic and connection factors
that match the entire U.S. Internet population. Currently, we're
calculating the number of people in the U.S. that visit any given Web
site each month (international usage calculations are in development).
Compete online metrics are leveraged by some of the largest companies
in the U.S. and often cited in publications like USA Today, Wall
Street Journal and The New York Times."
