*******************************************************
CAST is a complete introductory statistics textbook on a computer.
Interactive animations are used to explain all statistical concepts. CAST
is professionally produced and makes full use of the computer as a teaching
tool.
------------------------------------------------------------
What makes CAST stand out from other instructional material?
------------------------------------------------------------
* CAST takes a modern data-based approach to teaching statistical
methods. It is full of real data sets.
* Central to CAST are over 300 interactive diagrams. These are an
integral part of the text -- indeed they are the MAIN way that
the concepts and methods are explained.
* CAST covers all material in a statistical methods course (plus a
few!) with a minimum of mathematics.
* A separate version of CAST is available for lecturers, containing
only the interactive diagrams. These can be used to illustrate
points in lectures and retain student interest.
* No charge will be made for using CAST in the year 2000. We do
however reserve the right to make a small charge for registering
to use CAST in later years.

Accessing CAST
--------------
CAST requires a reasonably fast computer -- at least 150 MHz for acceptable
performance. It is accessed through a web browser such as Netscape
(versions 4.5, 4.61, 4.7 or later on a Macintosh or PC) or Microsoft
Internet Explorer (version 4.5 or later on a PC only). Enter the location
http://cast.massey.ac.nz in your browser.
You normally need to get a PIN code by registering before using CAST but a
temporary login name and PIN code are available until April. You may use
the login name "guest" and PIN code "1111" to try CAST, but don't forget to
register properly later -- you will certainly need to register after April.
This is the full version of CAST. You will be able to examine a brief
description of the contents of each page, but you are likely to find it too
slow to load the individual CAST contents pages if you access them through
the internet. (It works well with high-speed internet connections within
New Zealand but the international links are much slower.)
To speed up CAST, you will need to download it to a local hard disk (or a
local file or web server) to get good performance. Download CAST directly
from
http://www-ist.massey.ac.nz/CAST/CAST.zip (for a PC)
or
http://www-ist.massey.ac.nz/CAST/CAST.sit (for a Mac)
The download is about a 3.2 MB and the contents must be expanded using a
compression utility such as WinZip or Stuffit. After you expand the
downloaded archive, a directory called "CAST" will be created. In your
browser open the local file "CAST.html" within this directory to start CAST.
You will still need to login when you run CAST locally, but everything else
happens much faster -- almost instantaneously on a 350 MHz Pentium II.
