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. PROGRAM MAINS FEATURES ~~~~~~~~~~~~~~~~~~~~~~ SIMSTAT is a menu driven statistical program that provides many basic descriptive and comparative statistics including: o Summary statistics (mean, variance, standard deviation, etc.) o Crosstabulation - normal crosstabulation and inter-raters agreement table - nominal statistics (chi-square, Pearson's Phi, Goodman-Kruskall's Gamma, Contingency coefficient) - ordinal statistics (Kendall's tau-b and tau-c, Pearson's R, symetric and asymetric Somers' D, Dxy and Dyx) - inter-raters agreement statistics (percentage of agreement, Cohen's Kappa, Scott's Pi, Krippendorf's r and R-bar, free marginal correction for nominal and ordinal measure) - 3-D bar chart o Frequencies analysis including: - frequencies table - barchart NEW 2.0 - graphic pie chart - histogram (text or graphic) - descriptive statistics - percentile table NEW 2.0 - Box-and-Whiskers plot o Breakdown analysis NEW 2.0 - Multiple Box-and-Whiskers plot NEW 2.0 o Multiple responses analysis - frequency analysis - crosstab analysis NEW 2.0 o Time series analysis incluging - Data transformation (ex.: remove mean, lag, etc.) - Auto-correlation diagnostic (ACF and PACF plot). - Time series smoothing techniques (moving average, running median) o Oneway analysis of variance NEW 2.0 - Scheffe post hoc test. o Paired and independent sample t-tests o Pearson correlation matrix, covariance and cross product deviation o Regression analysis including: - Linear and 7 nonlinear regressions including: - quadratic - cubic - 4th degree polynomial - 5th degree polynomial - logarithmic - exponential - inverse - X and Y scatterplot (text or graphic) - regression equation - analysis of variance - residuals caseplot NEW 2.0 - standardized residuals scatterplot NEW 2.0 o Multiple regression analysis including: - 5 different regression methods: - hiearchical entry - forward selection - backward elimination - stewpwise selection - enter all variables - P to enter, P to remove, and tolerance criteria - anova table - test of change anova table - regression equation (B, standard error of B, beta, confidence interval of B, zero-order, semi-partial and partial correlations, tolerance level, F, significance) o Nonparametric analysis including: NEW 2.0 - Binomial test NEW 2.0 - One sample chi-square test NEW 2.0 - Runs test - Mann-Whitney U test - Wilcoxon T-test - Sign test - Kruskall-Wallis ANOVA NEW 2.0 - Friedman two way anova - Kolmogorov-Smirnov test for 2 samples NEW 2.0 - Kolmogorov-Smirnov test for 1 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 o bootstrap analysis - simulation on 7 univariate and 21 bivariate estimators: - descriptive statistics NEW 2.0 - histogram (text of graphics) - percentile table - nonparametric confidence intervals - nonparametric power analysis - variable sample size - random sampling simulation NEW 2.0 - full analysis bootstrap simulation NEW 2.0 o high-resolution graphics - Pie chart, 3-D bar chart, histogram, scatterplot, time series - User control of axis scaling, titles, grid, etc. - Graphics can be printed on almost any type of printers such as: - 9 and 24 pin dot matrix printers, - 9 and 24 pin color printers, - HP LaserJet, - HP DeskJet, - Deskjet 500c and 550c color printers, - PostScript printers, - HP PaintJet color printer, - HP pen plotters. - Graphics can be exported to PCX or HPGL graphic formats. OTHER FEATURES: NEW 2.0 o Integer weighting of cases using another variable. NEW 2.0 o Direct access to 4 user defined external data editors for each type of data file (Lotus, dBase, Ascii, SPSS/PC+). NEW 2.0 o Ability to assign missing value and variable label to any variable or to change the variable length and number of decimal used to display results. Ability to save and recall all those informations in a dictionnary file. NEW 2.0 o Ability to shell to DOS. NEW 2.0 o Ability to save and retrieve options files. NEW 2.0 o SIMEDIT spreadsheet data editor (SIMEDIT and SPSS/PC+ file format) - Import Lotus, dBase, SPSS/PC+ and ASCII file - Export dBase, SPSS/PC+, and ASCII file - IF-THEN-ELSE conditional variable tranformation with more than 47 operators and functions (numeric, trigonometric, statistics, random number and date function). - Undo last transformation. - Quick transform command for often used transformation. - Ability to assign variable/value labels and missing values. - Variable recoding, ranking, etc.. - Ability to sort cases. - Search and replace values. NEW 2.1 o Ability to customize a new Add-ins pulldown menu to run SIMSTAT add-in programs or other often used applications. NEW 2.1 o SIMCALC probability calculator computes probabilities for 9 types of test/distribution as well as confidence intervals for mean and correlation. (The registered version can also be used as a stand-alone 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.
