NOTE 1: The data sets from Wild & Seber (2000) are available at http://wiley.com/college/stat/wild329363/datasets/dataindex.html.
It is easy to use STATA or other softwares if the data sets are available.

NOTE 2: Looking for a nice, free, stats package? Try Statcrunch. You need to have a live internet connection, and will be asked to provide your email address, and you'll also need to take a little (very little) bit of time figuring things out (don't ask me!). But you can do all homework with this.

Here are some hints on how to read data into Stata.

In your browser, copy the link address.
In Stata, use command "insheet using " and paste the link address. (use command "clear" first if necessary.)
Type "help insheet" for help.
