Statist is a statistics program with an interactive menu that makes it very easy to use. It can also be run in scripts, and large data sets are handled reasonably well even on small machines. In spite of its low overhead, it can do quite a few regression functions and tests. It can produce colorized output, and uses gnuplot to create graphics.
