ScrCalc — TSR calculator can grab screen numbers and paste result. Manual expression entry too.

* * *

Old but good design. ScrCalc is a TSR calculator that performs all arithmetic operations and has a store-number-in-memory feature. Can grab numbers displayed in text mode ouput using its own cursor. Equations can also be entered manually. Uses 5K RAM when resident; no unload from memory option. Hot key is ALT +. Operation is simple but maybe not initially intuitive – read the doc first. Distributed as donationware.

Addit — TSR addition-only calculator.

* *

[updated 2006-08-21]

A simple addition calculator that runs as a TSR. You can pop it up in almost any text mode application and highlight numbers in your text you wish to add (vertical and horizontal highlighting possible). You can paste the result into the application. Because only the addition operation is supported, its use is limited. Plus the hot key is <ALT><LEFT SHIFT> which won't work in programs that grab the ALT key for menu access, etc. The TSR requires about 6.5K RAM and can be unloaded from memory.

VpCalc won't suit everyone's tastes, but it represents one of the more versatile freeware DOS calculators available. Technically speaking, VpCalc is a "variable precision floating decimal point calculator." It runs as a menu-less full screen application. Calculations are entered using variables. Includes mathematical, logical and conditional operators, plus the usual array of trigonometric functions. You'll need to read the manual or the online help to get a feel for how to enter equations and take full advantage of "code" (macro) files. Entering equations is not difficult &0150; just different; instead of entering "5 + 3 =", you type the expression "x = 5 + 3", and VpCalc returns and stores the value of x (variable values are automatically stored in memory). VpCalc can log all output to a text file. Several help screens available from within program.

CheX — Good checkbook program with graphing and check printing functions.

* * * * *

[added 2000-11-10]

CheX is a fairly intuitive checkbook program that has more features than most. For example, you can print out checks you enter into the program, and customize the layout to suit the layout of your real checks.

• Balance, Sort, Undo, Find, Auto-Save, Categories.
• Security / safety features: Password protection, lock option (posted items can't be altered), option to auto-exit after x minutes. Displays detected entry errors on status line.
• AutoCopy function eases copying of repetitive monthly items.
• Informative, context-sensitive status line. Good help function.
• Exports to comma delimited text format (easily imported into most spreadsheets / databases). Imports comma delimited, ASCII, or CheX files.
• Graphing capability (display totals by month, by year, or by category).
• Customizable (e.g., international date support option, auto-save, auto-exit, colors, cursor size, etc.)
• All this (and more) in an 83K executable.

Y2K date sorting warning: CheX stores and displays the century-year as two digits (e.g., "12-29-00"). CheX's sorting functions (F2 and F6-S) sort checks by date, and always assume 20th century years (19xx). Consequently, If you include checks with pre-Y2K dates (e.g., xx-xx-99), a check with date xx-xx-00 will fall before the xx-xx-99 check after a sort. Quick and dirty solution: Treat centuries as separate accounts.

The multi-column display includes these extras:

• A "check mark" column to indicate whether a check has cleared the bank. Both the balance in your account and the balance of the checks/deposits cleared by bank are displayed.
• Category column: optionally define categories for individual checks (e.g., charitable, medical, etc.)

• Save check book (and categories list) to an ASCII text file.
• Search function.
• Shell to DOS
• Multiple print options: entire check book; current page being displayed; from a certain page to the end of the check book; only checks in defined category.

• Max 1000 lines per data file.
• Check descriptions are limited to 26 characters.
• Credit and debit maximum value is 99999.99

Later DOS versions that use extended memory unfortunately do not run under the most recent incarnations of Windows 98 or Windows NT.

Author: David Meredith (1992).

DOS version is no longer developed. Shareware Windows 9x/NT and 2000/XP versions are available at the X(PLORE) Home Page.

I'm not well-qualified to evaluate these packages, but most are basic and not suitable for extremely large data sets. I've listed a range of programs which *together* cover most of the more familiar statistical tests, i.e., univariate/descriptive, anova, regression, t-test, and familiar nonparametric tests (Chi Square, Fisher's Exact..).

PEPI — Statistical package for epidemiology and other contexts.

unrated

[added 2000-01-30, updated 2004-08-25]

...43 easy-to-use programs with hundreds of menu-driven options and procedures. The programs can be run from a diskette or hard disk, in Windows (3.x, 95, 98 or NT) or DOS. They are primarily for use in the planning and statistical analysis of studies in the health field, but can be used in other contexts also. Many of the programs may be useful for learning or teaching purposes. The programs are interactive, generally offering a variety of options. Most of the programs are designed to facilitate secondary calculations after observations have been tabulated or counted, and nearly all require key board entry of data.

Notes: Includes program finders (for both DOS and Win3.1) that facilitate matching of executable name to statistical tests performed. Able to send results to file, printer, screen, or all. Free for personal use. Can be purchased on disks (with manual, installation program, more) from home page (link below). Also see home page for a long list of available statistical tests.

SST — (Simple Stats) Parametric / non-parametric stats program can output results / graphs to text file.

unrated

I like the simple, if primitive, layout of this program. No mouse or menus, but I find its interactive interface easy to use – and there are quite a few features under the hood, including the ability to send output (e.g., graphs) to a file as ASCII text. Unlike most of the packages listed here, SST contains a wide selection of both parametric and nonparametric statistical functions. Histograms and scatter plots are output as text by default, but you can optionally display or print these as hi-res graphics if your video card supports it. Documentation is a little strange.

• Descriptive statistics of all variables: mean, median, and mode(s) of each variable; standard deviation, coefficient of variation, mean deviation, low, high and n.
• Detailed chart of descriptive statistics for one variable. This includes n, variance, standard deviation, mean, RMS(quadratic mean), harmonic mean, geometric mean, mean deviation, median, coefficient of variation, skew, kurtosis, mode, low, high, range, sum, sum squared, standard error, Winsorized mean, and quartiles.
• Multiple linear regression based on least- squares linear fitting.
• Two variable t-test, chi-squared analysis, Pearson's contingency coefficient, Pawlik's corrected contingency coefficient, the sum of all rows and columns, and Cramer's V (for 2x2 tables).
• Two sample nonparametric tests: Kolmogorov-Smirnov, Mann-Whitney U test, Wilcoxon matched pairs, both Spearman's and Kendall's matched pair rank correlations, Wald-Wolfowitz runs test for unpaired samples, median test for independent variables Seigel-Tukey rank dispersion test.
• One-factor variance analysis from more than one variable (ANOVA). Confidence interval chart, and Wilcoxon rank sum analysis for two variables, or a Friedman test for more than two variables.

• Allows up to 5 variables and up to 480 numbers/variable.
• Program itself requires 512k RAM.
• Although I haven't had problems running this program on my 386 (MSDOS 6.2) it currently doesn't start on my OpenDOS system (...used to work.)

ISU (Interactive StatUnit) — Advanced statistical package.

unrated

[updated 2005-12-09]

ISU is an interactive shell which runs a general statistical unit developed by the author. ISU uses a large command set rather than menu options – this affords greater flexibility (e.g., data manipulation) than is possible with the other stats apps listed here. However, ISU is a more complex program and requires an in-depth familiarity with both the command set and statistics. Package includes the calculators Calc and T. Tutorial files and online help are very helpful. Includes Pascal source. Requires 80386+.

• Statistical tests: Summary statistics, two-sample Wilcoxon or Mann-Whitney test, Spearman's rank correlation, Bartlett's test for variance homogeneity, CORMAT writes the matrix of correlations for a set of variates, with optional indication of significances.
• Statistical models: analysis of variance and regression; multiplicative or log-linear models for Poisson or multinomial data; logistic regression models for binary or binomial data; nonlinear regression models and generalized linear models with over-dispersion; proportional hazards models by Cox's likelihood; conditional logistic regression.
• VGA graphing and histogram capability (printable on LaserJet, but no option to output to image file). Interactively rotatable 3D graphics can also be produced.
• Uses plain text data files. Can be configured to use external editor.
• Appends all results and command history to log file.

Author: Tue Tjur, Denmark (2001).

2001-02-22 release, last for DOS. Also available for Windows.

For a new installation of ISU, get all four files. To update an earlier version, get ISUPACK.BIN and ISUINST.EXE. Place needed files in the ISU directory, and then run the EXE. Advisory: Backup ISUPACK.BIN – it gets deleted at the end of installation.

STATS — Basic statistical program.

unrated

[updated 2004-08-05]

STATS is a basic full screen statistical program. Includes graphing functions. For a DOS program, it is not too difficult to use or navigate, although some commands are not easily located. Mono, CGA, EGA and VGA resolutions. Not mouse compatible. The Windows version is much easier to use, in my opinion.

1. User-editable one- and two-variable data sets.
2. Can draw scatter plots for any data sets. Text can be added to scattergrams.
3. Six automatic curve-fitting modes.
4. Binomial, Hypergeometric, and Normal distributions.
5. Summary statistics of data sets (can't be saved to a file, but can be printed).
6. Can save data sets in proprietary format for re-use, or as plain ASCII files.

1. 2-variable data sets are limited to arrays of twenty columns and 300 rows max.
2. Can't export plots or other graphics to files (you can print them).
3. Available key commands are scattered throughout documentation.
4. Has the Borland Pascal 7 CRT bug. See fixes.

HISTOGRAMS — Calculates descriptive statistics, generates histograms.

unrated

[updated 2004-08-05]

HISTOGRAMS is a mouse and menu-driven full screen app that only performs bare descriptive statistics on a user editable data set (max is 999 values, single variable). This app is too big (189K with support files) for the few functions it performs, but it is easy to use. "This program will calculate the mean, median, and standard deviation of a data set. It will also generate a histogram, a bar chart, a box and whisker plot, and a stem and leaf plot." You can save your data to a file, but not summary statistics. The low resolution histograms can be printed, but not exported to a file. This app can run in a DOS window.

[added 2002-07-28, updated 2004-08-05]

General Stats package, with a teaching emphasis. DOS and Win versions. Free for individual, non-commercial use.

Instat+ is designed to support the teaching of statistics. It includes features to help explain many of the key concepts, such as confidence intervals, that users often find confusing. Furthermore, our teaching menu provides a resource pack of ideas, some that use Instat+, but many that can be used with any statistical software.

Instat+ includes many special facilities for the processing of climatic data. These have formed the basis of numerous agroclimatology training courses, in the UK, Kenya, Niger, Algeria, Syria, the Philippines and elsewhere.

Released by the Statistical Services Centre, University of Reading, UK (1999).
