In an effort to determine the likelihood of an individual vaccinated against the H1N1 virus, we investigated how different social, economic, and demographic characteristics are associated with personal vaccination patterns using the National 2009 H1N1 Flu Survey Data from National Center for Immunization and Respiratory Diseases (NCIRD).

In effort to determine the likely author of the disputed federalist papers, we analyzed the text patterns in the Federalist Papers using principal component analysis, k-means clustering, and hierarchical clustering. Though results we got through PCA and hierarchical clustering are inconclusive, K-means clustering provided a promising clustering result. In our K-means algorithm, all of James Madison’s papers and the vast majority of the disputed papers are grouped into the the same cluster. Therefore, we conclude that most likely author of the disputed federalist papers is James Madison.
