- Look up the Kolmogorov-Smirnov (sp?) statistic in a more advanced
- statistics text than the ones you have now. This statistic is
- implemented in many of the major commercial stat packages, and is not
- hard to compute. (It is basically a software implementation of using
- probability paper.) Be forewarned, however, that the test is not
- very powerful against many alternative distributions, especially the
- ones that are "normal-like", so you might need a very large sample to
- do a reliable test.
