Welcome to the power program. Draft documentation for the program is available via this link.
As currently written, this program will handle 5 or fewer factors (a
five-way ANOVA), 25 or fewer levels (for example, it will handle an 8x8x8 three-way
ANOVA but not a 9x9x9 ANOVA), and 5000 or fewer observations. It
assumes that interactions are negligible. If you
have a more difficult problem, please contact Steve Verrill at the address
This is working as of 1/12/97, but it has not yet been thoroughly tested.
Which kind of test do you want to consider?
The PRE-SPECIFIED requirement is associated with a
statistical subtlety that a user might want to discuss with a statistician.
It involves the issue of ``multiple comparisons.''
