Bug:

ghthr() assumes the mu's are ranked from small to large.

The iterative procedure used in ghthr() is not waterproof. It assumes that the cross-over point between two distributions lies between [mu1 - sigma1 , mu2 + sigma2]. Intersections beyond this range (though very rare) are not found.

Revision History:

15 Dec 1993 by DVC

The dominance check that was included till now checked if either distribution dominated the other one at its mean value; this is a poor check. This check is replaced by dominance checking at the extreme mu+-sig points, which are now also the extremes for the iterative search procedure.
