SHAREWARE DESCRIPTION ~~~~~~~~~~~~~~~~~~~~~ SIMSTAT and its related programs are NOT public domain or freeware! The SIMSTAT package is a copyrighted software product developed and owned by Normand Peladeau. SIMSTAT is distributed as shareware. As such, individuals may evaluate the SIMSTAT package for a maximum period of 30 days. At the end of the evaluation period, if you find SIMSTAT to be a useful tool and wish to continue using it, you must register your copy with the author, Normand Peladeau. Registration entitles you to a copy of the current version of SIMSTAT and a free copy of the next version when it becomes available. This copy will be mailed to you as soon as it is released. Registered use also receive a printed and bounded manual and a minimum of 90 days of free support (by mail and via CompuServe). Registered users who have already received their upgrade of SIMSTAT may order the next version by paying a minimal fee. To register your copy of SIMSTAT, fill out the order form included in the distribution archive (the file called ORDER.FRM) and mail it with payment to the address specified on the form.

When starting Simstat, there are three command line options that can be used: /M or -M Force monochrome color set on a computer with a color card. /E or -E Display 43 lines on an EGA or 50 lines on a VGA monitor. /C or -C Save the listing file in a compressed format. This option is useful for saving disk space when running on a laptop. The listing file will take up to 75% less disk space. You must use the EXPAND.EXE utility to uncompress the listing file. CONFIGURING SIMSTAT TO WORK WITH EXTERNAL EDITORS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SIMSTAT can be configured to automatically call external data file editors in order to edit the current data file or to create a new file. It allows the specification of up to 4 externals programs corresponding to the four types of file currently supported (LOTUS, DBASE, SPSS/PC, and ASCII). For each of those types, enter the full name of the program or batch file including the drive and directory where it resides. You can also enter any parameters normally used when calling the program from the dos prompt. To automatically include the current filename put the $f keyword where you want the filename to appear.

(The registered version can also be used as a standalone program) INPUT AND OUTPUT ~~~~~~~~~~~~~~~~ The data may be read directly from a dBase file (version III or IV), a LOTUS 1-2-3 file, an SPSS/PC+ file or from an ASCII data file. The output can be read on the screen, save on disk in a listing file, and/or send directly to the printer. CAPABILITY ~~~~~~~~~~ The program can handle up to 500 variables and 32,000 cases. The simulation can contain between 50 and 20,000 subsampling. These limitations are the absolute maximums and can be somewhat lower depending on the amount of memory available. SYSTEM REQUIREMENTS ~~~~~~~~~~~~~~~~~~~ SIMSTAT will run on any IBM PC/XT, AT, PS/2 and compatible under MS-DOS/PC-DOS version 3.0 or higher. A minimum of 360K of free RAM is necessary. The program does not need a numeric coprocessor but will use it if available. A coprocessor is highly recommended for extensive bootstrap simulation or computation on large samples.

CREATING AND USING CUSTOMIZED MENUS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To simplify the use of SIMSTAT or for security reasons, it may be desirable to hide some functions or analyses from the user. The EDITMENU.EXE utility program allows you to create and edit customized pulldown menus and keep those definitions in a special file (.MNU extension). To run this utility program enter: EDITMENU {filename} where {filename} stands for the .MNU file you want to edit or create. Then, you can use the RETRIEVE OPTIONS command from within SIMSTAT to retrieve MNU files and change the current menu definition. You can also specify a menu definition by putting the following parameter when starting the program: SIMSTAT /L:{filename} This parameter can also be invoked automatically by using the following SET command before calling SIMSTAT: SET SIMSTAT = /L:{filename} Consult your DOS manual for more information on the SET statement. NOTE TO PROGRAMMERS ~~~~~~~~~~~~~~~~~~~ An application programming interface (API) for Simstat is currently under development. If you are a programmer interested in developing add-in programs to perform specific type of analysis currently not available in SIMSTAT, please contact the author (see address below). NONLIN -- Nonlinear Regression Program ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you like SIMSTAT but need a powerful nonlinear regression program that can perform statistical regression with general equations, I suggest you try the Nonlin program written by Phillip H. Sherrod. Nonlin is a powerful nonlinear regression program that can fit a general equation, whose form you specify using normal algebraic notation, to a set of data values. The fitted equation can include polynomial, exponential, log, square root, and transcendental functions including trigonometric, Bessel, Chebyshev polynomials. The fitted function may even be piecewise continuous. Nonlin can be used as a stand-along program or invoked as an "add-in" from SIMSTAT using the SIM2NL utility program. The shareware version of Nonlin is available from many BBS or you can contact the author at the address below. Nonlin version 2.2 or later is required for use with SIMSTAT.
