This release of

SYSTAT (now owned by SPSS) comes with a host of features.

In addition to its exhaustive set of statistical

procedures and functions, this version also includes

Partially Ordered Sets (POSAC), Perceptual Mapping,

Probit, Signal Detection analysis, and few other modules.

Installation is smooth,

except for the long 29-digit license code you have to

input. It opens with four default windows–Main,

Graph, Data, and Command Editor. The main window is for

results and error messages. The menu bar has three main

dropdown lists, each for manipulating data, graphs, and

statistics. The data menu has commands to transform data

or assign values to a variable by applying an expression.

You can use any mathematical expression including

variables, numbers, functions, and operators. You can

also use complex expressions joined by logical operators

AND, OR, NOT to assign values to variables. If you want

to transpose data, you can do it with the click of a

button. Now, the original variable names are stored in a

new variable called label$.

The Data window is the

most important element of the software. This is the

spreadsheet where you input all your tabulated data in

rows and columns. Each row represents one case or one

record, and each column represents one variable, from the

data set. You can specify up to 32,000 variables, and

there is virtually no limit to the number of cases or

records. You can enter data directly into the spreadsheet

or import existing data from dBase, SPSS, Lotus 123,

Excel, ASCII text files, and a few other formats. You can

export data to different file formats using the Save As

option. While importing dBase files, field names become

variable names. In the case of spreadsheets, data from

the first row will become the variable name. The merge

command is a convenient way to combine variables or

records from multiple files for analysis.

Variable names can be upto

12 characters long and are not case-sensitive. A

character variable is represented by a dollar ($) sign at

the end of its name. Once you define a numeric variable,

it cannot be changed to character and vice versa. SYSTAT

data can either be numeric or character strings. Maximum

display width of data is only 12 characters. A character

string cannot exceed this length. SYSTAT can read,

calculate, and store numeric values with more than 12

digits, but these values are either rounded off or

expressed in the exponential form for display in the Data

window. The value label is a convenient way to associate

numeric data with character strings and vice versa for

better understanding.

The Graph window lists all

the graphs created through various statistical procedures

in a sequential order. You have limited control in terms

of graph editing. You can save the charts into BMP, CGM,

EPS, JPEG, PICT, WMF, and SYG (SYSTAT) formats. You can

cut and paste the graphs to change the order.

The Command Editor is

useful once you become familiar with its syntax. This

requires a bit of work. You can record all the commands

that are executed from the Command Editor window for

reuse later. The command log is a temporary file keeping

track of all the commands you initiated during your

current session. You can open, edit, save, and re-execute

all commands stored in the command log at any time during

a session.

Help in SYSTAT is

exhaustive, listing all procedures available. Help also

discusses briefly each statistical procedure and provides

cross-reference. However, organization of Help file could

do with improvements.

This software gives you

complete freedom and flexibility to manipulate your data

through different statistical procedures, and graphs and

plots.
