Distribution Functions (v2.0)
Mark Von Tress, Ph.D.
March 13, 1994.

This Windows 3.1 program calculates several statistical distribution
functions and some simple power calculations. 

The new version adds better online help, the power function for
one way ANOVA;  Fisher's exact Test and its power function; one
and two sample t and z tests; Fisher's exact test and its power
function; the Wilcoxon Rank Sum Test in 2xK Tables, and its
power function. More tests and power functions are planned for
the future.

It requires Windows 3.1, and does not require a math
coprocessor. It takes about 2 megs of disk space, and
lzexpand.dll must exist in the Windows system directory.

I can't tell you how much it cost to write this program, but it
cost plenty. It is written in Borland C++ using the OWL 2.0 library
and the Protogen code generator 4.0. The help file was written using
Visual Help by Firas Bushnaq (CIS 70272,1656). The installation
program is SLS-SETUP(TM) by Stephen Sama (73313,2540).

If you like this program and use it often, please
send me $10 for the program. You may distribute it in full and unchanged.

////////////////////////////////////// Installation Instructions

Version 2 uses a Windows installation program that does a couple
of things for you:

      It copies all of the files to the places where they are needed. 

      It also creates a program manager group for you. 

      It does NOT modify the autoexec.bat, config.sys,
      win.ini, system.ini, or create its own .ini file in the windows
      directory. 

      It copies one file to \windows\system: ctl3dv2.dll.

      It also creates a directory on a target drive for the other
      files. 


Installation Options: You have the option of not installing
certian dll files if they are already on your hard drive. 

1.) The distribution files are required for this program, so
install them.

2.) The installation progam is needed since then recent upgrade(?) of
OWL only allows dynamic linking of modules, so the zipfile size
went from 160k to 700k to carry arround the extra baggage found
in the OWL 2.0 dlls. These dll's are usually found in the BC4.0
bin directory, so you don't have to install them if you already
have the required dll's. 

3.) I also use the Protogen code generator. It has some dll's that
are required. You don't have to reinstall these if you already
have them on your hard drive.

4.) If you already have ctl3dv2.dll in your windows\system
directory, then you can skip installing ctl3dv2.dll. 


The files are compressed using Compress.exe by Microsoft. These
files are automatically decompressed during installation using
c:\windows\system\lzexpand.dll which is usually supplied with
Windows 3.1. It must be present on your drive to expand the
compressed files. 


Installation steps:

1.) Copy all of the files, except the zip files, to a the root
directory of floppy or ram drive. Consider this your back up disk.

2.) If you are in DOS, change to the directory where you copied
the files and issue the DOS command

>win pd3setup

which cranks up the setup program from windows.

If you are in Windows, make the Program Manager the active
application, and go to the file menu (alt F). Then start
pd3setup using the run command. 

3.) The setup program will lead you through the installation.
The first dialog lets you select the source and target drives,
exit, select options, or install. If you select options, you can
trim the number of dll's you need according to the discussion
above. If you select the install button, then you are prompted
for the directory on the target disk to install the files. It is
\pd3\ by default, and you may change it. The installation
begins, and files are expanded. 

Note the meter dialog will end at 48% completion, which
represents the size of the compressed files copied over,
relative to the roughly 1.9 megs required for all of the
expanded files.
