I always understood that the runs test was designed to detect systematic
departures from the fitted line because some other curve fitted the data
better. In this context, it is a test for dependence of residuals.
There is a discussion of this at
http://216.46.227.18/curvefit/systematic_deviation.htm
Any elementary text in Non-parametric Methods in statistics will
give an example.
Hope this helps Jim Snow
