The
first
of
the
new
procedures
is
CLUSTER
which
pro-
vides
several cluster analytic techniques
falling
broadly
into
two
categories: hierarchical
tree
or linkage
methods
and
k-
means
splitting methods. Several graphical displays
provide
the
analyst
with
visual
feedback
on
the
effectiveness of
the
clustering procedures.
The
NP
AR
module
contains
most
of
the
commonly
used non-parametric procedures
including
a
sign
test,
the
Wilcoxon
signed
ranks
test,
the
Kruskal-Wallis
one-way
and
Friedman
two-way
ANOV
As
based
on
ranks
and
the
Kolmogovov-Smimov
one
and
two
sample
distribution
comparison methods. A
very
complete
time
series
module
provides
for
the
computation of
auto
and cross-correlation
coefficients, fourier
analysis
and
ARIMA
model
fitting
and
prediction.
To
perform necessary transformation,
the
data
can
be
smoothed
with
moving
averages,
medians
or
general
linear
filters
with
user
supplied
weights.
Another
nice
feature
is
the
speed
with
which
the
various
modules
execute their calculations. Interestingly,
the
author
told
me
that Systat
running
on
a micro-diskette equipped
Macintosh
was
faster
in
performing large-scale regressions
than
an
IBM-XT
equipped
with
a
hard
disk.
Upon
exiting
each
module
all
run
commands
from
the
current
session
are
printed automatically
to
provide
permanent
documentation.
Its
features
will
be
valued
by
users
in
professional research
and
business
environments.

Notes
ror
Jazz.
This
package
provides
useful
support
of
two
kinds
for
users
of
Lotus'
Jazz
package.
One
disk
provides
a
handy
set
of on-line
notes
to
assist
the
Jazz
user
while
the
second disk
contains
12
business
templates.
The
notes
contain information
that
can
help
both
the
novice
and
the
experienced
user.
The
notes
are
similar
to
the
II
About"
menus
provided
with
Microsoft products.
They
consist of
scrolling
windows
of
topics
which
summarize Jazz'
many
features.
InstaJJation.
Use
&
Documentation.
Both
the
Notes
and
the
templates
documentation
(called
Companion)
are
accessed
as
two
desk accessories installed
in
the
System
file
of
your
Jazz
start-up disk (or of
your
hard disk.)
You
do
not
use
Apple's
FontlDA
Mover
to
install
the
programs; rather,
an
easy-to-use installation
program
is
included
on
the
disk.
In
addition
to
the
desk accessories,
two
data
files
which
contain
the
text
for
the
accessories
must
be
moved
to
the
Start-up
disk,
all
of
which
is
done
automatically
by
the
installing
program.
If
you
should call
up
either desk
accessory
while
not
in
Jazz,
you
will
get a
message
that
you
must
be
running
Jazz
(with
your
serial
number)
in
order
to
use
the
programs.
Your
Jazz serial number
is
read
from
your
Master,
which
must
be
inserted
during
installation of
the
desk accessories.
In
addition
to
the
on-line
help,
the
programs
come
with
a shon
manual
containing
the
installation instructions.
Adding
the
DA's
to
a
hard
disk
is
a bit
trickier,
but went
smoothly
for
me.
I
successfully installed
Notes
onto:
a Jazz Master diskette, Jazz
moved
onto
Apple's
HD
20
and
Jazz
moved
onto
a
Lisa.
Description,
Since
Jazz
has
no
on-line
help
files,
an
omission
not
suffered
by
some
of
its
competition,
Notes
serves
a
useful
purpose.
It
provides
both
introductory
and
detailed information. For example, I
never
remember
which
parameters
go
where
in
different
functions.
Take
the
PMT
function
for
computing
interest
payments.
It
has
three
param-
eters
representing
the
principal, interest
and
period of
the
loan.
Notes
provides
a quick
look-up
to
remind
the
user
which
parameter
is
which.
The
screen shot
below
demonstrates
what
a
Notes
Help
window
looks
like.
The
three
topics
at
the
top
are
part of a
tree,
Beginning
is
the
highest
level
under
which
Worksheet
and
other options presented
themselves
at
the
bottom
of
the
window.
Selecting Worksheet brought
forth
another
set
of
selections of
which
Functions
was
my
choice.
As
you
can
see,
a selection can
now
be
made
of
which
type
of
function
Notes
are
desired.
Having
clicked
on
Time
&
Finance,
a
scrolling
window
listing
all
the
Notes,is
displayed.

Companion.
The
business
templates
provide
help
in
three
areas:
Accounting,
Finance
and
Administration.
While
I
did
not
evaluate everyone
for
accuracy,
the
ones
I
used
seemed
to
perform
acceptably.
Some
of
them
are
a bit simplistic,
e.g.,
the
Payroll
template
would
serve
only
the
smallest of
busi-
nesses
and
handles
only
the
computation of
pay
(i.e.
multi-
plying
hours
worked
for
each of several
rates
by
the
rate
and
making
a
few
subtractions
for
taxes
and
FICA).
There
are
tem-
plates
for
a
Cash
Journal,
Receivables
and
Payables.
The
finance
category includes
templates
for
profit
and
loss
analy-
sis,
cash
flow,
breakeven
analysis,
loan
amortization
and
depreciation. I
must
mention
that
the
accompanying
manual
contains
only
a
two
sentence,
description
of
each
template.
Summary.
My
overall
impression
was
that
the
notes
were
helpful
and
the
templates
well
designed.
However,
I
think
the
product
suffers
in
several
important
ways.
First,
even
at
an
introductory price of
$79,
it
is
a
bit
expensive
for
what
it
pro-
vides.
Second,
the
desk
accessories should
have
been
set
up
to
install
into
the
Jazz program, rather
than
in
the
System
file
where
they
take
up
two
precious
positions of
the
fifteen
permissible
desk
accessories.
Since
the
programs
only
work
with
Jazz,
it
seems
that
installation
in
Jazz
is
the
right
place
to
be.
In
this
way,
they
will
only
be available
to
you
when
you
are
in
Jazz.
Third,
the
installation
is
awkward
and
clearly
aimed
at
the
copy protection
issue.
Apparently,
the
package
will
read
your Jazz serial
number
and
write
it
to
the
Notes
disk,
thereby
preventing installations
on
other
Jazz
Masters.
I
can
appreciate
Layered's
not
wanting
the
program
to
be
used
in
an
unauthorized
way,
but
there
must
be
a better
way.
