  We recognize that many will want to acquire and use a much more
powerful statistical program than is represented by this freeware
product.  If you need a more advanced program, you may wish to
consider purchasing the "Statistical Package for the Personal
Computer" or SPPC program.  The SPPC contains all of the FREESTAT
procedures and a great deal more!  The remainder of this chapter
provides information about the SPPC program and how to order a
copy.

  The SPPC is a fast, accurate, simple to use, yet powerful data
analysis package that demands little of your computer, takes up a
minimum of space on your hard disk, and gives you a large number
of data analysis options.  It is menu driven throughout and very
fast on the most minimal of equipment.  The SPPC requires an IBM
XT, AT, PS/2 or fully compatible system using DOS 3.0 or higher
(requires a hard disk) with 640K of memory.

                         MAJOR FEATURES

  The SPPC includes a complete Data Manager, Frequency
Distributions, Summary Statistics, Crosstabs, Probability
Functions, Measures of Association, Elementary Regression,
Parametric Hypothesis Testing, Non-parametric Hypothesis Testing,
Correlation Matrix, Simultaneous Multiple Regression,
Hierarchical Multiple Regression, Analysis of Variance
capability, Statistical Potpourri, and a Printed User's Manual.

                           DATA FILES

  There is no limit to the number of cases you can have in any
data file and you can have up to 200 variables in any of them.
You can have your data files on any number of diskettes and
process all of them.  The SPPC data manager provides complete
support for creating, editing, and updating your data files.  You
can also create subfiles for those special analysis chores and
diskfile sorting is very convenient.

                          SAVED OUTPUT

  A very nice feature is one that stores all outputs for any
computer session.  When finished, you can send your final output
to the screen, your printer, or a permanent disk file.  This
feature is ideal for capturing final results to edit and merge
into other documents with your word processor.

                         SCREEN GRAPHICS

  If you have a CGA, EGA, or VGA monitor and board you will also
have instant high resolution graphics.  Create bar charts, column
charts, line graphs, scatterplots, and pie charts.  All of them
with legends, titles and other useful features.  Capture your
graphs as slides, as many as you like, and save them all for
later review or to move into documents with such powerful word
processors as Microsoft Word and Word Perfect.  The SPPC also
contains a Slide Show facility for presentation of graphical
analysis that you have performed and saved.

  If you wish to order a copy of SPPC, get back to DOS and from
the FREESTAT directory issue the command, ORDERIT.  Your computer
will then print an order form for you.
