STPLAN.HQX
Note: is also a MSDOS executable version I have not been able
to run as
yet due apparently to lack of memory.

/* concerning this software. */
INTRODUCTION
STPLAN performs power, sample size, and related calculations
needed to
plan studies. Parameters of a test include those necessary
to
describe the distributions under the null and alternative
hypotheses,
sample sizes, significance levels, and power. Given values
for all
but one parameter, STPLAN will calculate the value of that
one
parameter.
HOW IT WAS WRITTEN
STPLAN was largely written in FLECS+, a Fortran preprocessor,
similar
in spirit to ratfor. The resulting ugly Fortran was polished
with the
Toolpack tools, pol and decs. We wish that we could claim
that it
passed the pfort portability test, but pfort runs out of
steam on
anything the size of STPLAN.
LEGALITIES (BRIEF)
We want to make this program as widely available as possible.
Hence, executable code derived from the source provided,
the source
itself, and the accompanying documentation may be freely
copied and
distributed provided that this copyright section accompanies
such
copies. We encourage the distribution of this code on bulletin
boards
and as shareware.
Modifications and improvements to the code can similarly
be freely
copied and distributed. Barry Brown would appreciate a copy
of any
such improvements for incorporation into later versions
of STPLAN.
Source code may be extracted and used for any non-commercial
purpose. Non-commercial means that at most a modest distribution
fee
is charged, as shareware. We would appreciate acknowledgment
of usch
use of our code.
Commercial use of the source code requires written permission
from
the Department of Biomathematics at the above address. Our
policy is
generally to grant such permission provided appropriate
credit is
given to us in the documentation.
