[STATISTICS, DOS]
	Einsight is a powerful statistical package that 
is designed to tackle the problem of extracting useful 
information from multivariate data.  This program is an 
exploratory data analysis system that calculates and then 
graphically displays patterns of association in multivariate 
data sets.  This type of analysis is useful for life 
scientists because so much of the data collected in nature 
is not univariate. 
	Einsight uses a windows like interface that is easy 
to learn and understand.  The main input device is the mouse.  
Once your data is plugged in, (and you can import from many 
different software platforms)  all you need to do is point 
and click.  This is makes it easy for even the novice user 
to be up and running in little time. 
	The graphics in Einsight will allow you to display 
multiple windows with individual tables or tables and multiple 
plots in single windows.  There is an icon bar located on the 
right hand side of the screen that makes the choices easy.  
One option allows the user to spin the 3D plots to any 
direction desired.  Any window can display any graphic which 
is appropriate for the data object in that window.  For 
example, a scatter plot containing two scores from principal 
components can be changed to a rotating 3D plot by making 
that window active and choosing that option from the menu 
bar.  The windows can also be resized by pulling on the 
mouse.  This makes it easy to see in greater detail the data 
set on which you are currently working. 
	Einsight has dendrograms, line plots, multiplot, 
and as mentioned before 3D rotating plots.  The reason for 
all of these graphs is to aid you in interpreting your data 
and to determine if there is any underlying structure that is 
not apparent from a less in depth examination.  This is the 
reason for the four windows with multiple graphs.  The software 
prods you to explore your data and then move in on the 
relationships that may exist. 
	One aspect of data analysis that Einsight is very 
helpful with is of identifying outliers. Because of the 
versatility of the graphing, deciding if a sample is 
representative or not is easy.  The software has a walkthrough 
that teaches this skill. 
	Einsight was easy to install and should not give any 
problems.  However it appears to run very well on a 386 
with no math co-processor.  The only problem 
at this time seems to be speed.  A math co-processor is 
recommended for those of you who can't bear to wait.  The 
learning curve with this software is short,  most should be 
able to be productive after just a short time.  One of the 
high points of this software is that you do not have to be 
a math wizard to understand the relationships that the 
software is showing.  This gives the researcher more power 
over his or her own work. 
	There wasn't  any problem to speak of with this 
software.  This is an old version and one would bet that 
improvements have been made,  but this reviewer found Einsight 
very practical and easy to use.
