Large and feature-rich data sets are made available by the U.S. government or its subsidiaries on the Internet. For instance, see the Centers for Disease Control and Prevention data sets (www.cdc.gov/DataStatistics), Surveillance, Cancer.org’s Epidemiology and End Results data sets (http://seer.cancer.gov/data), and the Department of Transportation’s Fatality Analysis Reporting System crash data sets (www.nhtsa.gov/FARS). These data sets are not preprocessed for data mining, which makes them a great resource to experience the complete data mining process. Another rich source for a collection of analytics data sets is listed on KDNuggets.com (kdnuggets.com/datasets/index.html).
