The 32 bit version of Simstat for Windows (see detailed description below)
has entered its final beta testing and is expected to be released this
summer. We would like to obtain as much feedback as possible on how the
program currently works and information on remaining bugs.

OUTPUT MANAGEMENT FEATURES
~~~~~~~~~~~~~~~~~~~~~~~~~~
SIMSTAT Notebook window is used to displays the statistical output
for all analyses performed during a session. The notebook metaphor
provides an efficient way to browse and manage ouptuts.
o The text output of each analysis is displayed on a separate page.
You can turn pages either with the mouse by clicking on the page
corner icons at the bottom of the notebook or by using the <PgUp>
and <PgDn> keyboard keys.
o While each page can be annotated or edited, it is also possible
to add empty pages for recording ideas or remarks, sketching an
analysis plan, or writing down interpretation of results.
o Tabs may also be added to create sections in the notebook,
allowing you to store different types of analysis in different
sections of the notebook.
o An index of all analysis in the notebook is also provided.
This index can be used to quickly locate and go to a specific
page, move pages within the notebook, or delete some pages.
SCRIPTING/MULTIMEDIA FEATURES
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
o Script commands automate statistical analysis, data filtering
and transformation.
o RECORD SCRIPT feature automatically generates commands corresponding
to operations performed with menus and dialog boxes.
o Flow control features such as IF-THEN-ELSE statements, GOTO or
GOSUB commands, commands to run external programs (DOS and Windows),
or execute another script.
o Can read, write, and perform mathematical operations on user defined
variables or any database variable.
o Creates menus, text boxes, input boxes, dialog boxes, multiple items
questions, etc. (responses from a user can be stored in memory
variables or in a data file).
o Multimedia features: plays sound (.WAV), music (.MDI), and movie
(.AVI) files, displays graphics (.BMP, .ICO, .WMF) and text.
GRAPHIC FEATURES
~~~~~~~~~~~~~~~~
The Charts window displays all high-resolution charts created
during a session.
o Full control of axis, labels, legends, colors, line drawing, etc.
o 3-D view, rotation and zooming features
o Charts can be copied to clipboard or saved to disk as picture (.BMP),
Windows Metafile (.WMF), or tab separated values.
BONUS FEATURE
~~~~~~~~~~~~~
o SIMCALC probability calculator computes probabilities for 9 types
of test/distribution as well as confidence intervals for proportions,
mean, and correlation. This utility program also computes contingency
table statistics and inter-raters agreement statistics from data table.
SYSTEM REQUIREMENTS
~~~~~~~~~~~~~~~~~~~
SIMSTAT will run on any Win 9x/NT system. A minimum of 16MB of free RAM
and only 3MB of disk space are required.
