- I don't know of any software, but Lillefors's test is relatively simple, and
- described in many texts. Kolmogorov's test, which was the basis for Lillefors's,
- requires that you _completely_ specify the distribution (including mean and
- variance). Lillefors relaxed this requirement.
-
- If you have a spreadsheet with the Gaussian CDF available as a function,
- you can program it to perform this test easily. Good luck!
