Comments about the Summer Institute

Not only is Penn State’s Methodology Center considered one of the best statistical training centers in the country, but the center is funded by the National Institute on Drug Abuse—because of this, they can attract well-known speakers who are leaders in substance-use research. This provides a great environment in which we can learn and network.
