1. Introduction and System Requirements
ANALYSIS is a time-series analysis package which includes a
wide diversity of transformations and other techniques to
locate and quantify patterns in a data set. Even though you
may not be analyzing time-series data, ANALYSIS can still
give the same kinds of information as might be extracted
from time dependent events, however, the interpretation
changes. The only requirement is that you simply have the
data in ASCII single column format. Some types of analyses
also require that you specify two data sets. You will easily
know which modules require this by the directions on the
first menu screen for each type of analysis. If you are
required to import two data sets, you must concatenate them
into a single file which is of course twice as long as each
original file.
There are two other general requirements to use this
package.
1) The first is simply that you should have installed the
ANSI.SYS in your CONFIG.SYS file. This was probably already
done for you depending on your version of DOS, but just the
same take a peak at the CONFIG.SYS file. This is a normal
text file, so if you have to edit it be sure to save the
file in text mode and avoid any special control characters
that a word processor might put in it. Check to see if you
have in your CONFIG.SYS file, a line which reads:
DEVICE=ANSI.SYS
if you don't, edit the file and add this line to it. You can
still run ANALYSIS without ANSI.SYS, but the cursor control
used by this package is dependent on the ANSI standard and
will probably behave a bit strange without it.
2) The second requirement is that your screen be at least
640 by 480. As with the ANSI.SYS requirement, ANALYSIS will
still run on smaller screens, but some of the graphic
displays may clip on screens much smaller than this. Give it
a try.
2. Registration
ANALYSIS is distributed through a unique marketing concept
called "shareware". The idea behind shareware is that you
get the software and try it for a short grace period and if
you intend to use it beyond that you register your copy with
the author. The entire concept is based on an honor system
among programmers and users, which has led to an outstanding
base of high quality software without the high price usually
associated with it. Also, shareware users are in the unique
position of being able to contact the authors of the
software they are using and get direct support in the form
of manuals, phone help, and possible further customization
of the software. Please read the list of added features you
will receive when you become a registered user of ANALYSIS.
2.1. What do I get when I register ANALYSIS?
Most authors of shareware offer further features to
registered users. Below is a list of the additional items
provided to registered users of ANALYSIS.
2.1.1. Upgrades - What's next?
Registered users of ANALYSIS pay a one time registration
price and receive all upgrades free. The only cost is a
minimal fee to cover the postage and handling of the disk.
As a registered user you will receive notifications through
the mail for updates of ANALYSIS.
Several users have asked what is in store for new versions
of ANALYSIS. Since in general we update ANALYSIS every 8-10
months, I will simply provide a broad sketch of planned
upgrades.
Most users have commented that, above all, they would like
to see more "number crunching" routines with as much
flexibility as possible. In light of this, the following
additions will be made to the next version(s) of ANALYSIS:
1) WAVELET - Additions to the wavelet module have already
begun. These include a broader family of "mother wavelets",
which can be viewed prior to use. We are also looking into
algorithms for allowing the user to define their own "mother
wavelet".
2) NON-LINEAR ANALYSIS - Several routines have already been
written to estimate quantities such as the correlation
dimension and Lyapunov exponents of an attractor. These are
quantities used to characterize the geometry and dynamics of
a system's attractor. They can thus be used to determine if
a system is chaotic or not.
3) MODELING - Both linear and nonlinear modeling in the form
of ordinary differential equations (ODEs). The idea here is
to specify a general form of the ODEs and solve for the
parameters by using optimality constraints on the fit and
stability of the equations.
4) STATISTICAL TESTS - Some users have requested the
inclusion of various statistical tests such as ANOVA and T-
tests. We did not plan to incorporate much in the way of
statistics beyond the first four moments and distribution,
but considering the feedback obtained from our users, a
general section for additional statistics will be added in
the future.
We encourage all our users to provide feedback about
ANALYSIS along with any ideas they may have for future
releases. This is the primary means by which we guide our
updates.
2.1.2. User's Manual and Tutorial
A laser-printed user's manual and tutorial which is actually
and expanded version of section 3 of this file will be given
to all registered users. This manual includes various
examples of data analysis and explains which techniques are
best in certain circumstances and the type of information
which can be obtained from such methods. Several graphic
examples are also used to assist the reader in the
interpretation of the results obtained from using ANALYSIS,
along with an extended list of references for future
reading.
2.1.3. Direct Support
All registered users of ANALYSIS will receive full support
either over the telephone, internet, or via the regular
mail, by using one of the contact points on the cover of
this document. This information is also listed on the first
information screen of the program as well. Typical support
consists of addressing any problems which are encountered
while running ANALYSIS on certain machines. NOTE: The
leading cause of reported problems is simply not using the
proper file format. Please refer to the screen accompanying
the particular module you are using for any additional
requirements on file format beside those already stated.
2.2. ANALYSIS Registration Form
There is a separate form in the file REGISTER.DOC, which is
the registration form. To get a hardcopy of the file you can
"copy" it to your printer by using C:>COPY REGISTER.DOC
PRN. This command prints out the document assuming the
REGISTER.DOC file is in the C:\ directory. You do not have
to use this form, but try to include the following
information when registering ANALYSIS:
