This is s.qcount, version 0.5B <02 Jan 1995> Copyright (c) 1993-1995. James Darrell McCauley The tutorial for this program is in s.qcount-tutorial.ps.Z (zcat s.qcount-tutorial.ps.Z | command_to_print_PostScript). The man page should have been installed automatically. If you don't have a PostScript printer, there is LaTeX source code in the tutorial directory (If you don't have LaTeX OR a PostScript printer, see if someone will print/mail you a copy). Let me know if there are bugs (esp with respect to rand()). Enjoy. --Darrell James Darrell McCauley, Purdue Univ, West Lafayette, IN 47907-1146, USA mccauley@ecn.purdue.edu, mccauley%ecn@purccvm.bitnet, pur-ee!mccauley P.S. it seems that in Cressie's text (see tutorial), there is a factor of n missing before the summation in the numerator. I sent him email about it and am awaiting confirmation.
