Data sets: Some lecture examples will feature data from published research, books, or other sources; I'll try to make the data available here so you can try out the methods used in class or experiment with other methods. Also some homework problems will have data sets; I'll put those here too. Click on any item below and you will find either the raw data or a further page of explanation leading to the raw data. Use the Save As feature of your web browser to save the data to a file, which you can then enter into R using the read.table command.
