Short: Statistical Analysis using TurboCalc 5 (update 3) Author: (Rudy Kohut and Nick Bergquist) Uploader: kohutr connexus net au (Rudy Kohut) Type: misc/math Version: 2c (Almost ready for Release) Replaces: TCalcStats2b.lha Requires: OS2.04+, RexxMast; rexxmathlib.library (included); reqtools.library (included); TurboCalc 5+ (it may work on ver. 4); Latest version of Installer (included) Architecture: generic Distribution: Aminet Date of this release: Sometime during August 1999 *************** Changes in version 2c: * Addition of one new script: - Durbin.rexx (Durbin Test - Incomplete Block Design) * Changes to the HELP files and Stats_Macros.TCD macrosheet to reflect the new script. I have also cleaned up the html code. *************** *************** Changes in version 2b: * Addition of three new scripts: - Chi-Sq_GO_Fit.rexx (Goodness of Fit test) - this complements the included "Normality" test which is also based on the Chi-Sq Test - Shapiro.rexx (Shapiro-Wilk Test for Normality) - Deviates.rexx (Random Normal Deviates Generator) * Changes to the HELP files and STATS_Macros.TCD macrosheet to reflect the new scripts. I have also added material in the HELP files related to the "Normality" test, linking it with the new "Goodness of Fit" test material. I would appreciate feedback/assistance on this as my ability to interpret the Chi-Sq tests is limited and text books are very confusing! (Rudy) *************** *************** Changes in version 2a: * Corrections to two scripts: - T-test_IndSamples_UneqVar.rexx (silly editing error corrected) - Fisher_Exact.rexx (programming error corrected) * Addition of two new scripts: - Cochran.rexx (Cochran's test for related observations) - Smirnov_2W.rexx (Smirnov test on two independent samples) * Changes to the HELP files and STATS_Macros.TCD macrosheet to reflect the new scripts ************** What is it? This archive contains a number of Arexx script files (32!) that are called by TurboCalc macros to produce statistical analysis on data contained in a spreadsheet.

Read the included help files! NOTE: We have not been able to finish the help files and some of the scripts for this release. However, it is about 98% complete and still usable. Changes? This is the second version of TcalcStats. It replaces the first version developed for use with TurboCalc 3.5. This version uses Turbocalc 5+ but may also work with TurboCalc version 4 (untested). Please note: there were some changes made to the Arexx command set in TurboCalc between 3.5 and 4/5. Also, TurboCalc's public screen name changed. These changes, along with many, many, others are reflected in the scripts. What is included? There are basically four categories of files in this distribution: 1. The Arexx script files that do the work and which MUST be put in the TurboCalc/Arexx drawer. 2. The spreadsheet file that contains the macros that call the scripts (called "STATS_Macros.TCD", and which can be put anywhere but will be installed in the TurboCalc/arexx drawer. 3. The help files that tell you how to use the macros and interpret the results! These files would normally be put in the Turbocalc/Help/Stats_Help drawer but you can install them anywhere. We have tried to produce two types of help files - Amigaguide and HTML. They are identical (we hope!) so choose which one you prefer. 4. Special arexx library files that must go in "Libs:". These are: >rexxreqtools.library< copyright 1992-94 by Rafael D'Hallewyn >rexxmathlib.library< copyright 1995 by Thomas Richter Installation? Use the supplied "Install_Tcalcstats2c" program to put things in their proper places. It is also vital that you have an "Assign" for Turbocalc. If the installer doesn't find one, it will prompt you to create the assign and add it to your "user-startup" file. The assign must be active or the scripts will not work!! Who did it? Rudy Kohut did the first version by himself (and it shows!). Rudy and Nick Bergquist teamed up to improve and expand the scripts and to create vastly improved help files in both amigaguide and HTML formats. Rudy lives in Melbourne, Australia. Nick lives in Greenwich, U.K. Any queries? Please give us your feedback! Contact Rudy by email: kohutr@connexus.net.au Contact Nick by email: N.A.Bergquist@greenwich.ac.uk
