I apologize for the brevity of my previous message. It was my first
attempt.
B-stat is a full fledged statistics program, including multiple
regression
Anova, discriminant analysis, factor analysis, non-parametric tests,
etc.
It has everything usually found in a general stat package, but it has a
superior regression component (includes weighted, Huber, ridge,
principal
components, logit, cook's d, Farrar-Glauber, etc). It also has a nice
time series component. The data editor is spreadsheet style, with many 
powerful data transformation capabilities. The program can import data
from lotus wks, ascii, prn, dif and sylk files.
    The graphics package is the best I have seen on the ST. It really
can
do most of what Harvard Graphics can do (if you have Gdos - but not
required). Many graph types (bar, line, scatter can be mixed and 
matched, 3-d bar, pies, component pies, hi-low stock graphs, polar
graphs, horizontal, opposed bars, floating bars, star, box and whisker,
and others I don't remember. Text can be moved with the mouse, and can
be of different sizes, vertical or horizontal, arrows can be drawn, line
thickness and fill patterns can be varied by variable, etc. In other
words, very flexible. Can output .gem files for importation into dtp
such
as Timeworks dtp or easydraw (text included) or pagestream and calumus
(text
ignored). The author wants $30 US, and sends a 200 page manual with
registration. Currently, program is in uncompiled Gfa 3.0, but it should
be compiled soon. It is surprisingly fast. A 1040 holds about 26000 data
points, about 100000 in a 2 meg. I have been beta testing it for the
author.
I wanted a program like this for a long time on the ST. It is available
now on genie or compuserve. I would upload it here but I don't know how.
I would be willing to mail a disk to someone who would volunteer to
upload
it to the net. Send to liebo@csclea.ncsu.edu  or mail to
