USERS NEEDED
------------
This program is a beta version of a basic statistics and simulation
program (bootstrap simulation analysis will be available in the final version).
It is fully functional but may contain a few bugs and some design flaws.
In order to identify and fix them, I have decide to distribute it through
bulletin boards to interested users. I you use it and encountered any
problem, please let me know by providing me step-by-step instructions on
how to reproduce the problem, and, if necessary, the data set you were
running. Also, if you have questions, comments or suggestions about this
program don't hesitate to contact me (addresses at the end of this file).
The current version of this program is being distributed as user-supported
software. If you find this program to be of value, a voluntary contribution
would be appreciated. All contributors will be notified of updates and new
releases of the program as they become available. A contribution of $20 or
more will entitle you to a free upgrade.
All users who contribute significantly to the final revision of the
program, by their comments and suggestions, will also receive a free upgrade
and will be notified of program updates and product releases.
FILES YOU SHOULD HAVE
---------------------
Before you start working with SIMSTAT, take a few moments to check the
content of the archived file. The program should include 8 files:
1 text file
README.TXT -- This file.
3 files for the main program
SIMSTAT.EXE -- The simstat statistical program.
SIMSTAT.DEF -- The simstat default configuration file.
SIMSTAT.HLP -- The simstat help file.
4 sample data files
SAMPLE.DAT -- A sample Ascii data file.
SAMPLE.SYS -- A SPSS/PC+ system file.
SAMPLE.DBF -- A Dbase III data file
SAMPLE.WKS -- A Lotus data file.
1 utility file
EXPAND.EXE -- A program to uncompressed listing files
INSTALLING AND RUNNING THE PROGRAM
----------------------------------
To install the program, simply copy all the files to the destination
disk or directory.
There are three command line options that can be used with SIMSTAT:
/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.
PROGRAM MAINS FEATURES
----------------------
SIMSTAT is a menu driven statistical program that provide many basic
descriptive and comparative statistics.
o Summary statistics (mean, variance, standard deviation, etc.)
o Crosstabulation
- normal crosstabulation and inter-raters agreement table
- nominal statistics
- ordinal statistics
- inter-raters agreement statistics
o Frequencies analysis including:
- frequencies table
- barchart
- histogram
- descriptive statistics
- percentile table
o Breakdown analysis
o Oneway analysis of variance
o Paired and independent sample t-tests
o Pearson correlation matrix, covariance and cross product deviation
o Regression analysis including:
- X and Y scatterplot
- regression equation
- residual plot
o Nonparametric analysis including:
- Mann-Whitney U test
- Wilcoxon T-test
- Sign test
- Kruskall-Wallis ANOVA
- Kolmogorov-Smirnov test for 2 samples
- Moses test of extreme reactions
- Median test (2 or more samples)
o nonparametric association matrix including
- Spearman's R
- Sommer's D, Dxy and Dyx
- Goodman Kruskall's Gamma
- Kendall's Tau-a, Tau-b
- Kendall Stuart's Tau-c
PROGRAM SPECIAL FEATURES (will be included in the final version)
------------------------
The final version of SIMSTAT will also provide bootstrap simulation
analysis base on resampling procedure for 7 univariate and 20 bivariate
estimators. The program output will allow the examination of the estimator
distribution in various format including:
- descriptive statistics
- frequency table
- histogram
- percentile table
- Type I or Type II error rates (power estimate) for three
alpha level (0.10, 0.05 and 0.01).
INPUT AND OUTPUT
----------------
The data may be entered directly from the keyboard or may be read
directly from a dBase file (version III or IV), a LOTUS 1-2-3 file,
a SPSS/PC+ file or from a ASCII data file. The keyboard entry may be
saved for later analysis.
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 30,000 cases. The
simulation can contain between 100 and 20000 sub-sampling or permutation.
Those limitations are the absolute maximum 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 2.0 or higher. A minimum of 356K 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 with large samples.
SIMSTAT take less than 110K of disk space (including the help file).
It can easily be run on a system with a single 360K disk drive or on a LAPTOP
computer.
