-fhcomp- implements Fisher-Hayter pairwise comparisons. It makes use
of -gsturng- and - sturng1- through -strung8- that were included with
-prcomp- (STB-47) written by John R. Gleason of Syracuse University.
It was written specifically for use in a research methods course that
uses the textbook "Experimental Design" by Roger E. Kirk. Kirk makes
extensive use of the Fisher-Hayter approach in the text.
The help file for -fhcomp- seems to be missing several crucial pieces
of information including the citation to John R. Gleason's work noted
above. The other necessary piece of information is that -fhcomp- is to
be used after the -anova- command.
Examples:
. anova y b
. fhcomp b
. fhcomp b, level(.99)
/* differences in b at a==3 */
. anova y a b a*b
. fhcomp b if a==3
. fhcomp b if a==3, nu(36) sigma(7.6)
I apologize for the confusion caused by the help file and for the
missing citation.
